December 1994
54F 74F676
16-Bit Serial Parallel-In Serial-Out Shift Register
General Description
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 (P0 – P15) inputs is entered on the falling edge of the
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
