C is used to determine the dynamic power dissipation (P in W): PD D Data storage 2 2 P = (C x V x f ) + (C + V x f ) + (I x V ) D PD CC i L CC o pull-up CC Delay line. where: f = input frequency in MHz. i GENERAL DESCRIPTION f = output frequency in MHz. o V = supply voltage in V. CC The HC/HCT7731 are high-speed C = output load capacitance in pF. L Si-gate CMOS devices. They are I = pull-up currents in A. pull-up specified in compliance with JEDEC standard no. 7A. 2. For HC the condition is V = GND to V The HC/HCT7731 are quad 64-bit I CC For HCT the condition is V = GND to V - 1.5 V. I CC static shift registers with a recycling mode. Each register has separate 3.

Each recycling NUMBER PINS PIN POSITION MATERIAL CODE mode input controls two registers REC for registers A and B and ab 74HC/HCT7731N 16 DIL plastic SOT38Z REC for registers C and D. When cd 74HC/HCT7731D 16 SO16 plastic SOT109A 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. September 1993 2
