1. SCOPE
1.1 Scope. This drawing documents two product assurance class levels consisting of high reliability (device classes Q and M)
and space application (devic e class V). A choice of case outlines and lead finishes are available an d are reflected in the Part or
Identifying Number (PIN). When available, a choice of Radiation Hardness Assurance (RHA) levels are reflected in the PIN.
1.2 PIN. The PIN is as shown in the following examples:
For device classes M and Q:
5962 - 89735 01 R A
Federal RHA Device Case Lead
stock class designator type outline finish
designator (see 1.2.1) (see 1.2.2) (see 1.2.4) (see 1.2.5)

designator (see 1.2.1) (see 1.2.2) designator (see 1.2.4) (see 1.2.5)
\ / (see 1.2.3)
\/
Drawing number
1.2.1 RHA designator. Device classes Q and V RHA marked dev ices meet the MIL-PRF-38535 specified RHA levels and are
marked with the appropriate RHA designator. Device class M RHA marked devices meet the MIL-PRF - 38535, appendix A
specified RHA levels and are marked with the appropriate RHA designator. A dash (-) indicates a n on-RHA device.
1.2.2 Device type(s). The device type(s) identify the circuit function as follows:
Device type Generic number Circuit function
01 54ACTQ273 Octal D type flip-flop with reset,
TTL compatible inputs
1.2.3 Device class designator. The device class designator is a single letter identifying the product assurance l evel as listed
below. Since the device class designator has been added after the original issuance of this drawing, device classes M and Q
designators will not be included in the PIN and will not be marked on the device.

1/ For tests not listed in the referenced MIL-STD-883, (e.g. ΔICC), utilize the general test procedure under the conditions listed
herein. All inputs and outputs shall be tested, as applicabl e, to the tests in table I herein.
2/ Each input/output, as applicable, shall be tested at the specified temperature, for the specified limits. Output terminals not
designated shall be high level logic, low level logic, or o pen, except for the ICC and ΔICC tests, the output terminal shall be
open. When performing the ICC and ΔICC tests, the current meter shal l be placed in the circuit such that all current flows
through the meter.
Additional detailed information on qualified devices (i.e. pin for pin conditions and testing sequ ence) is available from the
qualifying activity (DCSS-VQC) upon request.
3/ RHA parts supplied to this drawing are tested through all levels M, D, P, L, and R of irradiation. Pre and Post irradiation
values are identical unless otherwise specified in table I. When performing post irradiation electrical measurements for any
RHA level, TA = +25°C.
4/ For negative and positive voltage and current values, the sign designates the potential differenc e in reference to GND and
the direction of current flow, respectively; and the absolute value of the magnitude, not the sign, is relative to the minimum
and maximum limits, as applicabl e, listed herein. All devices shall meet or exceed the limits specified in table I, as
applicable, at +4.5 V VCC +5.5 V.
5/ RHA samples do not have to be tested at -55°C and +125°C prior to irradiation.
6/ When performing post irradiation electrical measurements for RHA level, TA = +25°C. Limits shown are guaranteed at
T
A = +25°C ±5°C.
7/ Transmission driving tests are performe d at VCC = 5.5 V with a 2 ms duration maximum. This test may be performed using
VIN = VCC or GND. When VIN = VCC or GND is used, the test is guaranteed for VIN = 2.0 V or 0.8 V.
8/ Power dissipation capacitance (CPD) determines the no load power consumption, PD = (CPD + CL) (VCC x VCC) f
+ (ICC x VCC) + (n x d x ΔICC x VCC). The dynamic current consumption, IS = (CPD + CL) VCCf + ICC
+ (n x d x ΔICC). For both PD and IS, n is the number of device inputs at TTL levels, f is the frequency of the input signal, d
is the duty cycle of the input signal, and CL is the output load capacita nce.
9/ This test may be performed either one input at a time (preferred method) or with all input pins simultaneously at
V
IN = VCC - 2.1 V (alternate method). When the test is performed using the alternate test method, the maximum limit is
equal to the number of inputs at a high TTL input level times 1.6 mA; and the preferred method and limits are guaranteed.

10/ This test is for qualification only. Ground and VCC bounce tests are performed on a non- switching (quiescent) output
and are used to measure the magnitude of induced noise caused by other simultaneously switching outputs. The test is
performed on a low noise bench test fixture. For the device under test, all outputs shall be loaded with 500Ω of load
resistance and a minimum of 50 pF of loa d capacitance (see figure 4). Only chip capacitors and resistors shall be used.
The output load components shall be located as close as possible to the device outputs. It is suggested that, whenever
possible, this distance be kept to less than 0.25 inches. Decoupling capacitors shall be placed in parall el from VCC to
ground. The values of these decoupling capacitors shall be determined by the device manufacturer. The low and high
level ground and VCC bo unce noise is measured at the q uiet output using a 1 GHz minimum bandwidth oscilloscope
with a 50Ω input impedance.
The device inputs shall be co nditioned such that all outputs are at a high nominal VOH level. The device inputs shall
then be conditioned such that they switch simultaneous ly and the output under test remains at VOH as all other outputs
possible are switched from VOH to VOL. VOHV and VOHP are then measured from the nominal VOH level to the largest
negative and positive peaks, respectivel y (see figure 4). T his is then repe ated with the same outputs not under test
switching from VOL to VOH.
The device inputs shall be co nditioned such that all outputs are at a lo w nominal VOL level. The device inputs shall then
be conditioned such that they s witch simult aneously and the output under test remains at VOL as all other outputs
possible are switched from VOL to VOH. VOLP and VOLV are then measured from the nominal VOL level to the largest
positive and negative peaks, respectively (see figure 4). This is then repeated with the same outputs not under test
switching from VOH to VOL.
11/ Tests shall be performed in s equence, attributes data only. Functional tests shall inclu de the truth table and other logic
patterns used for fault detection. The test vectors used to verify the truth table shall, at a minimum, test all functions of
each input and output. All possible input to output logic patterns per function shall be guaranteed, if not tested, to the truth
table in figure 2 herein. Func tional tests shall be performed in sequence as approved b y the qualifying a c tivity on qualified
devices. After incorporating allowable tolerances per MIL-STD-883, VIL = 0.4 V and VIH = 2.4 V. For outputs, L 0.8 V, H
2.0 V.
12/ See JESD 17 for electrically induced latch-up test methods and procedures. The values listed for Vtrigger, Itrigger and Vover,
are to be accurate within ±5 percent.
13/ AC limits at VCC = 5.5 V are equal to limits at VCC = 4.5 V and guaranteed by testing at VCC = 4.5 V. Minimum AC limits for
VCC = 5.5 V are 1.0 ns and guaranteed b y guardbanding the VCC = 4.5 V minimum limits to 1.5 ns. F or propagati on delay
tests, all paths must be tested.
