SN74AC373NS Description

The SN74AC373NS is a high-performance, octal D-type transparent latch designed by Texas Instruments. This logic IC chip is part of the 74AC family, known for its advanced CMOS technology that combines the speed of equivalent bipolar devices with the low power consumption of CMOS. The SN74AC373NS features eight D-type latches with transparent latch function, making it ideal for applications requiring high-speed data storage and transfer. The device is available in a 20-lead small outline (SO) package, which is both compact and suitable for dense PCB layouts.

SN74AC373NS Features

• High-Speed Operation: The SN74AC373NS operates at a maximum clock frequency of 50 MHz, ensuring rapid data capture and storage. This high-speed capability makes it suitable for demanding applications where quick data processing is essential.
