General Purpose CMOS Logic IC

8bit Static Shift Resister

BU4021BF

General Description

BU4021BF is an 8bit static shift resister.It consists of eight

resister stages and each register has an parallel input. A

serial input/serial output function or a parallel input/serial

output function can be selected by a parallel/serial input

selection pin (P/S).

(Note 1) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 4.5mW per 1°C above 25°C.

Caution:

Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit

between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated

over the absolute maximum ratings
