MC14043B, MC14044B
CMOS MSI
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.

ORDERING INFORMATION
Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
1. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
See detailed ordering and shipping information in the package
dimensions section on page 5 of this data sheet.
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, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.
