IW4043BN Overview

quad 3-state R/S latches high-voltage silicon-gate cmos

TECHNICAL DATA
IW4043B
Quad 3-State R/S Latches
High-Voltage Silicon-Gate CMOS
The IW4043B types are quad cross-coupled 3-state CMOS NOR
latces. 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 “1” or high on the ENABLE input connects the latch states to the Q
outputs. A logic “0” or 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 busing of the outputs.
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1
μA
at 18 V over full package-temperature
range; 100 nA at 18 V and 25°C
Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply
