The PI74FCT373T and PI74FCT573T are 8-bit wide octal transparent latches designed with 3-state outputs and are intended for bus oriented applications. When Latch Enable (LE) is HIGH, the flip-flops appear transparent to the data. The data that meets the set-up time when LE is LOW is latched. When OE is HIGH, the bus output is in the high impedance state.
The PI74FCT373T and PI74FCT573T are fast CMOS octal transparent latches with 3‑state outputs, designed for bus‑oriented applications. They are pin‑compatible with Pericom’s earlier bipolar FAST™ series but operate at higher speed and lower power consumption.
The document provides detailed electrical characteristics, maximum ratings, switching timings, mechanical dimensions for multiple package types (TSSOP, SSOP, QSOP, SOIC) and ordering codes. It also includes typical power‑supply currents and propagation‑delay specifications for various load conditions.
