Overview
The SN74ALS373ADWRG4 from Texas Instruments is a high-performance Octal Transparent D-Type Latch with 3-state outputs. This integrated circuit is part of the Advanced Low-Power Schottky (ALS) logic family, known for its balanced compromise between speed and power consumption. It is designed to offer high reliability and performance for a wide range of digital applications, particularly in bus-oriented systems.
The device features eight latches with three-state outputs, allowing for the creation of buses of data. The latches hold the data inputs when the latch-enable (LE) input is high and store the data that was present one setup time before the LE transitioned from high to low. When LE is low, the latches are transparent, and data passes through them unaffected.
