Military product compliant to MIL-STD-833, Class B
Description
The IDT6116SA/LA is a 16,384-bit high-speed static RAM organized
as 2K x 8. It is fabricated using high-performance, high-reliability CMOS
technology.
Access times as fast as 15ns are available. The circuit also offers a
reduced power standby mode. When CS goes HIGH, the circuit will
automatically go to, and remain in, a standby power mode, as long as CS
remains HIGH. This capability provides significant system level power and
cooling savings. The low-power (LA) version also offers a battery backup
data retention capability where the circuit typically consumes only 1µW to
4µW operating off a 2V battery.
All inputs and outputs of the IDT6116SA/LA are TTL-compatible. Fully
static asynchronous circuitry is used, requiring no clocks or refreshing for
operation.
The IDT6116SA/LA is packaged in 24-pin 300mil plastic DIP, 24-pin
600mil and 300mil ceramic DIP, or 24-lead gull-wing SOIC providing high
board-level packing densities.
Military grade product is manufactured in compliance to MIL-STD-883,
Class B, making it ideally suited to military temperature applications
demanding the highest level of performance and reliability.

Timing Wa vef orm of Write Cyc le No. 1 (WE Controlled Timing)(1,2,5,7)
Timing Wa vef orm of Write Cyc le No. 2 (CS Controlled Timing)(1,2,3,5,7)
NOTES:
1. WE or CS must be HIGH during all address transitions.
2. A write occurs during the overlap of a LOW CS and a LOW WE.
3. tWR is measured from the earlier of CS or WE going HIGH to the end of the write cycle.
4 . During this period, the I/O pins are in the output state and the input signals must not be applied.
5. If the CS LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in the high-impedance state.
6. Transition is measured ±500mV from steady state.
7. OE is continuously HIGH. If OE is LOW during a WE controlled write cycle, the write pulse width must be the larger of tWP or (tWHZ + tDW) to allow the I/O drivers
to turn off and data to be placed on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the write pulse
is the specified tWP. For a CS controlled write cycle, OE may be LOW with no degradation to tCW.

Datasheet Document History
01/07/00 Updated to new format
Pg. 1, 3, 4, 10 Added Industrial Temperature range offerings
Pg. 9, 10 Separated ordering information into military, commercial, and industrial temperature range offerings
Pg. 11 Added Datasheet Document History
08/09/00 Not recommended for new designs
02/01/01 Removed "Not recommended for new designs"
12/30/03 Pg. 3,10 Corrected Industrial temp from -45C to -40C.
03/31/05 Pg. 10 Added "Restricted hazardous substance device" to ordering information.
11/15/06 Pg. 3 Changed power limits for commercial and industrial on speed grades 25ns and 35ns.
Pg.4 Changed power limits for commercial and industrial on speed grade 45ns. Refer to
PCN SR-0602-02.
04/26/11 Pg.1,2,3,4,6,10 Updated "Restricted hazardous substance device" to "Green". Obsoleted 24-pin SOJ, 24-pin 600 mil
and 35ns, 45ns for Industrial & Commercial.
05/01/13 Pg. 1 Description paragraph 4, package information. Changed text to read "The IDT6116SA/LA is packaged
in 24-pin 300mil plastic DIP, 24-pin 600mil and 300mil ceramic DIP, or 24-lead gull-wing SOIC providing
high board-level packing densities". Removed IDT in reference to fabrication.
Pg. 3 Updated DC Elec Chars (VCC = 5.0V ± 10%) table by adding industrial to the Test Conditions.
Updated DC Elec Chars (VCC = 5.0V ± 10%, VLC = 0.2V, VHC + VCC - 0.2V) table by removing the LA power
for the 15ns speed.
Pg. 10 Removed footnote "*Available in 300mil packaging only" from the Military ordering information.
