General description
The HEF4044B is a quad R/S latch with 3-state outputs, with a common output enable
input (OE). Each latch has an active LOW set input (1S to 4S), an active LOW 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. It is
also suitable for use over the industrial (
