Product specification

Quadruple 64-bit static shift register

HEF4731B; HEF4731V

LSI

DESCRIPTION

The HEF4731B and HEF4731V are quadruple 64-bit static

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.
