CD4021BC

8-Stage Static Shift Register

All inputs are protected against static discharge with diodes

General Description

to V_DDand V_SS

The CD4021BC is an 8-stage parallel input/serial output

shift register. A parallel/serial control input enables individ-

ual JAM inputs to each of 8 stages. Q outputs are available

from the sixth, seventh, and eighth stages. All outputs have

equal source and sink current capabilities and conform to

standard “B” series output drive.

Features

■ Wide supply voltage range: 3.0V to 15V

■ High noise immunity: 0.45 V_DD(typ.)

■ Low power TTL compatibility:

When the parallel/serial control input is in the logical “0”

state, data is serially shifted into the register synchronously

with the positive transition of the clock. When the parallel/

serial control is in the logical “1” state, data is jammed into

each stage of the register asynchronously with the clock.

Fan out of 2 driving 74L or 1 driving 74LS

■ 5V–10V–15V parametric ratings

■ Symmetrical output characteristics

■ Maximum input leakage 1 µA at 15V over full tempera-

ture range
