STMicroelectronics M74HC373TTR Octal D-Type Latch

The M74HC373TTR from STMicroelectronics is a high-speed CMOS octal D-type latch that is designed to be used in a wide variety of digital applications. This integrated circuit features eight latches with three-state outputs for bus-organized systems. The device comes in a TSSOP package, which is optimized for reduced space and power consumption in electronic circuits, making it an ideal choice for compact and energy-efficient designs.

Each latch of the M74HC373TTR is transparent; that is, the data on its input becomes available at its output when the latch-enable (LE) input is HIGH. The data is retained when the LE input is LOW, and the output will remain stable. Additionally, the device has an active-low output enable (OE) control, which when pulled low, places the eight outputs in a high-impedance OFF-state. This high-impedance state ensures that the outputs will neither load the bus when the device is not selected nor interfere with the operation of other devices connected to the bus.

Manufactured with silicon gate C2MOS technology, the M74HC373TTR guarantees high performance and reduces power consumption significantly compared to traditional latches. It has a broad operating voltage range from 2V to 6V, providing compatibility with TTL logic levels and making it suitable for interfacing with microcontrollers and other logic families within its voltage range.

The device is characterized for operation from -55°C to +125°C, ensuring reliability and functionality across a wide range of environmental conditions. This makes the M74HC373TTR an excellent choice for demanding applications in automotive, industrial, and consumer electronics where robust performance is required.

With its advanced features, the M74HC373TTR is an essential component for projects that require high-speed latching capabilities. It is well-suited for applications such as memory address latching, data storage, multiplexing, and as a buffer for interfacing to bus lines in a variety of digital systems.
