74F676 Datasheet | Philips Semiconductors

FEATURES - 16-bit parallel-to-serial conversion - 16-bit serial-in, serial-out - Chip select control - Power supply current 48m A typical - Shift frequency 110MHz tyical - Available in 300mil-wide 24-pin Slim DIP package DESCRIPTION The 74F676 contains 16 flip-flops with provision for synchronous parallel or serial entry and serial output. When the mode (M) input is High, information present on the parallel data (D0- D15) 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 information 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. The 16 bit shift register operates in one of three modes, as indicated in the shift register Function Table. Hold: A High signal on the Chip Select (CS) input prevents clocking and data is stored in the 16 registers. Serial load: Data...
