GENERAL DESCRIPTION
The HC/HCT7731 are high-speed
Si-gate CMOS devices. They are
specified in compliance with JEDEC
standard no. 7A.
The HC/HCT7731 are quad 64-bit
static shift registers with a recycling
mode. Each register has separate
data inputs D
a
to D
d
, clock inputs CP
a
to CP
d
and data outputs Q
a
to Q
d
.
Data shifts one place towards the
output, each LOW to HIGH transition
of the clock pulse. Each recycling
mode input controls two registers
REC
ab
for registers A and B and
REC
cd
for registers C and D. When
the REC input is HIGH, the device is
in the recycling mode and data at the
output is shifted back into the input of
the register, so after 64 clock pulses
the contents of a register is again in
its original position. This enables the
user to tap off data from any position.
When the REC input is LOW external
data can be shifted in.
