STMicroelectronics 74LVC373AMTR Octal Transparent Latch

The 74LVC373AMTR from STMicroelectronics is a high-performance, low-voltage CMOS octal transparent latch with 3-state outputs. It is part of the LVC (Low-Voltage CMOS) family, which is designed for operation at a nominal voltage of 3.3V. This integrated circuit is optimized for use in 3.3V systems but is also 5V tolerant, allowing for interfacing with 5V logic without the need for external level shifters.

Featuring eight latches with three-state outputs for bus-oriented applications, the 74LVC373AMTR is suitable for buffering data on the bus lines. Each latch has a separate LE (latch enable) input and OE (output enable) input, providing flexibility and control in data transfer and storage.

This device is capable of driving 24mA at the 3.3V supply voltage, ensuring good signal integrity and strong output drive capability. Additionally, the 74LVC373AMTR guarantees operation from -40°C to +85°C, making it suitable for industrial temperature ranges.

One of the key features of the 74LVC373AMTR is its low power consumption, with a typical quiescent current of only 2µA, making it an ideal choice for power-sensitive applications. Moreover, the device supports live insertion and withdrawal (partial power-down mode) without glitching, ensuring that systems can be maintained and updated without powering down.

The 74LVC373AMTR is offered in a TSSOP-20 package, providing a compact footprint for space-constrained applications. It is also available in tape and reel packaging, denoted by the 'TR' suffix, which facilitates automated assembly processes for high-volume production.

In summary, the STMicroelectronics 74LVC373AMTR provides a reliable and efficient solution for data latching in a wide range of applications, including telecommunications, computing, and industrial control systems. With its robust feature set and compatibility with existing 5V systems, it represents a versatile option for designers looking to enhance their digital logic operations.
