The CD54HC373F from Texas Instruments is a high-speed CMOS logic octal transparent D-type latch with three-state outputs. This integrated circuit is designed to offer the functionality of the HC373 logic family with the added benefit of a wide operating voltage range and the robustness of CMOS technology.

The device features eight latches with three-state outputs for bus-oriented applications. Each latch is D-type, meaning it has a data input, an output, and a control input. The transparent nature of the latches means that when the latch enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the data that was present at the inputs at the time of the transition is retained at the outputs until LE is returned high.

Additionally, the outputs can be placed in a high impedance state by applying a high logic level to the output enable (OE) input, making it suitable for interfacing with bus lines in a system. This feature allows for the direct connection of the outputs to a bus without the need for external pull-up resistors.

The CD54HC373F operates over a broad voltage range from 2V to 6V and features inputs that are pin-to-pin compatible with LSTTL outputs. This makes it an ideal choice for interfacing with traditional TTL devices while benefiting from the low power consumption and high noise immunity characteristic of CMOS devices.

The device is encapsulated in a ceramic flat package, ensuring durable performance in a wide range of environmental conditions. Its performance is guaranteed over the full temperature range of -55°C to 125°C, making it suitable for demanding applications in the industrial, automotive, and military sectors.

With its combination of high-speed operation, wide operating voltage range, and robust packaging, the CD54HC373F from Texas Instruments is an excellent choice for designers looking to implement reliable latching mechanisms in their digital systems.
