CMOS QUAD 3-STATENOR R/SLATCHES

DESCRIPTION

UTC UCD4043B types are quad cross-coupled 3-state CMOS NOR latches.  Each latch has a separate Q output and  individual SET and RESET inputs.
The Q outputs are controlled by a common  ENABLE  input. 
A logic  high  on   the  ENABLE input connects the latch states to the Q outputs. 
A logic low on the ENABLE input disconnects the latch  states from the Q outputs,  resulting in an open circuit condition on the Q outputs. 
The open circuit feature allows common bussing of the outputs. 

FEATURES

* 3-state outputs with common output ENABLE

* Separate SET and RESET inputs for each latch

* NOR configurations

* 5V, 10Vr and 15V parametric ratings

* Standardized symmetrical output characteristics

* Maximum input current of 1uA at 18V over full package temperature range; 100nA at 18V and 25°C
