CD4043BM/CD4043BC Quad TRI-STATE

NOR R/S Latches

CD4044BM/CD4044BC Quad TRI-STATE

NAND R/S Latches

General Description

Features

Wide supply voltage range

Low power

3V to 15V

CD4043BM/CD4043BC are quad cross-couple TRI-STATE

CMOS NOR latches, and CD4044BM/CD4044BC are quad

cross-couple TRI-STATE CMOS NAND latches. Each latch

has a separate Q output and individual SET and RESET

inputs. There is a common TRI-STATE ENABLE input for all

four latches. A logic ‘‘1’’ on the ENABLE input connects the

latch states to the Q outputs. A logic ‘‘0’’ on the ENABLE

input disconnects the latch states from the Q outputs result-

100 nW (typ.)

High noise immunity

0.45 V

(typ.)

Separate SET and RESET inputs for each latch

NOR and NAND configuration

TRI-STATE output with common output enable

Applications

ing in an open circuit condition on the Q output. The

TRI-STATE feature allows common bussing of the outputs.

Multiple bus storage

Strobed register

Four bits of independent storage with output enable
