1 / 6 page © 1999 Fairchild Semiconductor Corporation DS009588 www.fairchildsemi.com April 1988 Revised August 1999 74F676 16-Bit Serial/Parallel-In, Serial-Out Shift Register General Description The 74F676 contains 16 flip-flops with provision for syn- chronous parallel or serial entry and serial output. When the Mode (M) input is HIGH, information present on the parallel data (P0–P15) inputs is entered on the falling edge of the Clock Pulse (CP) input signal. When M is LOW, data is shifted out of the most significant bit position while infor- mation present on the Serial (SI) input shifts into the least significant bit position. A HIGH signal on the Chip Select (CS) input prevents both parallel and serial operations. Features s 16-bit parallel-to-serial conversion s 16-bit serial-in, serial-out s Chip select control s Slim 24 lead 300 mil package Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
