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 Da to Dd, clock inputs CPa

to CPd and data outputs Qa to Qd.

Data shifts one place towards the

output, each LOW to HIGH transition

of the clock pulse. Each recycling

mode input controls two registers

RECab for registers A and B and

RECcd 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.

QUICK REFERENCE DATA

GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW):

PD = (CPD x VCC2 x fi) + (CL + VCC2 x fo) + (Ipull-up x VCC)

where:

fi = input frequency in MHz.

fo = output frequency in MHz.

VCC = supply voltage in V.

CL = output load capacitance in pF.

Ipull-up = pull-up currents in µA.

2. For HC the condition is VI = GND to VCC

For HCT the condition is VI = GND to VCC − 1.5 V.

3. See also power dissipation information.
