TC74AC299F Datasheet 8-Bit PIPO Shift Register

Manufacturer: Toshiba

Overview: TC74AC299P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC299P, TC74AC299F 8-Bit PIPO Shift Register with Asynchronousclear The TC74AC299 is an advanced high speed CMOS 8-BIT PIPO SHIFT REGISTER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It has a four modes (HOLD, SHIFT LEFT, SHIFT RIGHT and LOAD DATA) controlled by the two selection inputs (S0, S1). When one or both enable ( G1 , G2 ) are high, the eight I/O outputs are forced to the high-impedance state; however, sequential operation or clearing of the register is not affected. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
