ON Semiconductor MC74HC373AN Octal D-Type Latch

The MC74HC373AN from ON Semiconductor is a high-performance, octal D-type latch that is designed to interface directly with the high-speed performance requirements of modern digital systems. This integrated circuit is fabricated with silicon gate CMOS technology, which ensures a reliable operation and compatibility with a wide range of applications in the electronics industry.

With its octal D-type transparent latches and three-state outputs, the MC74HC373AN is capable of storing eight bits of data. The device features a common Latch Enable (LE) input and a common Output Enable (OE) input, which simplifies the control of data acquisition and output. When LE is held high, the data on the D inputs is transferred to the latch outputs. Conversely, when LE is low, the latches retain their previous state, effectively storing the data. The OE input controls the three-state outputs and ensures that the outputs are either in a high-impedance state or actively driving the bus.

This latch operates over a broad voltage range from 2V to 6V and is characterized for operation from -55°C to 125°C, making it suitable for use in a variety of environmental conditions. The low power consumption and high noise immunity of CMOS technology, coupled with the ability to drive 10 LSTTL loads, make the MC74HC373AN highly versatile and suitable for interfacing with TTL logic levels.

The device is packaged in a standard 20-pin DIP (Dual In-line Package), which makes it easy to integrate into a wide range of electronic circuits. The MC74HC373AN is commonly utilized in applications such as memory address latching, data storage, multiplexing, and as a buffer for driving buses in digital systems.

ON Semiconductor's commitment to quality and reliability is evident in the MC74HC373AN, making it a preferred choice for designers and engineers looking for a dependable solution for their digital latching needs.
