Quad 3-State R/S Latch
High-Voltage Silicon-Gate CMOS
The SL4043B 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
A 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

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range
GND
(V
IN
or V
OUT
)
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
).
Unused outputs must be left open.
