1. General description
The HEF4043B is a quad R/S latch with 3-state outputs with a common output enable
input (OE). Each latch has an active HIGH se t input (1S to 4S), an active HIGH reset input
(1R to 4R) and an active HIGH 3-state output (1Q to 4Q).
When OE is HIGH, the latch outpu t (nQ) is d etermine d by the nR and n S input s as shown
in Table 3. When OE is LOW, the latch outputs are in the high impedance OFF-state. OE
does not affect the state of the latch. The high impedance of f-state fea ture allows common
bussing of the outputs.
It operates over a recommended VDD power supply r ange of 3 V to 15 V r eferenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
2. Features and benefits

5 V, 10 V, and 15 V parametric ratings
Standardized symmetrical outp ut characteristics
Specified from 40 C to +85 C
Complies with JEDEC standard JESD 13-B
3. Applications

Table 8. Dynamic power dissipation PD
PD can be calculated from the formulas shown. VSS = 0 V; tr = tf
20 ns; Tamb = 25
C.
Symbol Parameter VDD Typical formula for PD (W) where:
PDdynamic power
dissipation 5 V PD = 1100 fi + (fo CL) VDD2fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VDD = supply voltage in V;
(fo CL) = sum of the outputs.
10 V PD = 4400 fi + (fo CL) VDD2
15 V PD = 11400 fi + (fo CL) VDD2
tr and tf are the input rise and fall times.
Logic levels: VOL and VOH are typical output voltage levels that occur with the output load.
Transition times: transition time (tt) = HIGH LOW (tTHL) or LOW HIGH (tTLH) transition times.
Measurement points are given in Table 9 and test data is given in Table 10.
