Overview: TC74ACT299P/F
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74ACT299P, TC74ACT299F 8-Bit PIPO Shift Register with Asynchronous Clear The TC74ACT299 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.
This device may be used as a level converter for interfacing TLL or NMOS to High Speed CMOS. The inputs are patible with TTL, NMOS and CMOS output voltage levels.
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.
