HEF4043B
Quad R/S latch with 3-state outputs
Rev. 11 — 24 March 2016
Product data sheet
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 set 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 output (nQ) is determined by the nR and nS inputs 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 off-state feature allows common
bussing of the outputs.
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits
