54F/74F676

16-Bit Serial/Parallel-In, Serial-Out Shift Register

General Description

Features

16-bit parallel-to-serial conversion

The ’F676 contains 16 flip-flops with provision for synchro-

nous parallel or serial entry and serial output. When the

Mode (M) input is HIGH, information present on the parallel

data (P –P ) inputs is entered on the falling edge of the

16-bit serial-in, serial-out

Chip select control

Slim 24 lead 300 mil package

Clock Pulse (CP) input signal. When M is LOW, data is shift-

ed out of the most significant bit position while information

present on the Serial (SI) input shifts into the least signifi-

cant bit position. A HIGH signal on the Chip Select (CS)

input prevents both parallel and serial operations.
