Quad R−S Latches
The MC14043B and MC14044B quad R−S latches are constructed
with MOS P−Channel and N−Channel enhancement mode devices in
a single monolithic structure. Each latch has an independent Q output
and set and reset inputs. The Q outputs are gated through three−state
buffers having a common enable input. The outputs are enabled with
a logical “1” or high on the enable input; a logical “0” or low
disconnects the latch from the Q outputs, resulting in an open circuit at
the Q outputs.
Features
• Double Diode Input Protection
• Three−State Outputs with Common Enable
• Outputs Capable of Driving Two Low−power TTL Loads or One
Low−Power Schottky TTL Load Over the Rated Temperature
Range
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These Devices are Pb−Free and are RoHS Compliant

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Packages: –7.0 mW/_C From 65_C To 125_C
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 V
SS
≤ (V

or V

) ≤ V

.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
