Quadruple 64-bit static shift register

Product specification

HEF4731B; HEF4731V

LSI

DESCRIPTION

The HEF4731B and HEF4731V are quadruple 64-bit static

shift registers each with separate serial data inputs (DA to

DD), clock inputs (CPA to CPD) and data outputs (O63A to

O63D) from the 64th register position.

Recommended supply voltage range for HEF4731B is 3 to

15 V and for HEF4731V is 4,5 to 12,5 V.

Data are shifted to the next stage on the negative-going

transitions of the clock. Low impedance outputs are

provided for direct interface to TTL.
