CD4043 - CD4044

Quad 3-STATE NOR R/S Latches •

Quad 3-STATE NAND R/S Latches

General Description

The CD4043BC are quad cross-couple 3-STATE CMOS

NOR latches, and the CD4044BC are quad cross-couple 3-

STATE CMOS NAND latches. Each latch has a separate Q

output and individual SET and RESET inputs. There is a

common 3-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 discon-

nects the latch states from the Q outputs resulting in an

open circuit condition on the Q output. The 3-STATE fea-

ture allows common bussing of the outputs.

Features

s Wide supply voltage range:

3V to 15V

s Low power: 100 nW (typ.)

s High noise immunity: 0.45 VDD (typ.)

s Separate SET and RESET inputs for each latch

s NOR and NAND configuration

s 3-STATE output with common output enable

Applications

• Multiple bus storage

• Strobed register

• Four bits of independent storage with output enable

• General digital logic

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
