TC74ACT373P/F/FT is a high-speed CMOS 8-bit latch from Toshiba. It features low power consumption and high-speed operation. The chip uses 2-layer metal, silicon-gate CMOS technology and has TTL level inputs, which can be directly connected to TTL level buses. The chip consists of 8 independent latches controlled by a common latch enable signal (LE) and an output enable signal (OE). The output can be set to high impedance state by a high level OE signal, which makes it easy to interface with the bus. In addition, all inputs are equipped with diodes to protect the device from electrostatic damage.
The TC74ACT373 is an octal D‑type latch with three‑state outputs, designed with 2‑layer metal, silicon‑gate CMOS technology for high‑speed operation and low power consumption. It accepts TTL‑level inputs and provides independent latch control via common enable (LE) and output‑enable (OE) signals.
