TC74ACT299P/F is a high-performance CMOS 8-bit PIPO shift register produced by TOSHIBA. It has high speed and low power consumption, and can be used as a TTL or NMOS to high-speed CMOS interface converter.
The TC74ACT299P/F is an 8‑bit parallel‑in‑parallel‑out shift register fabricated with Toshiba's C2MOS technology. It offers high‑speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation, making it suitable as a level converter for TTL, NMOS, or CMOS interfaces.
