STMicroelectronics 74VHC373 Octal D-Type Latch with 3-STATE Outputs

The 74VHC373 is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology. It is an octal D-type transparent latch designed by STMicroelectronics that combines low power consumption with a high-speed interface, making it a suitable choice for a wide range of data storage and control applications.

This integrated circuit features eight latches with three-state outputs for bus-oriented applications. The device comes in a 20-lead package and is designed to be used as a temporary storage device by holding data that can be accessed by the outputs. Each latch is controlled by the latch enable (LE) and output enable (OE) inputs. When the latch enable input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

A high on OE causes the outputs to assume a high impedance OFF-state. Operation of the OE input does not affect the state of the latches. This feature allows the 74VHC373 to be used in bus-oriented systems where multiple devices can share a common bus line without the risk of data collision.

The 74VHC373 operates at a voltage range of 2V to 5.5V, providing a flexible power supply requirement which is compatible with most TTL families. Additionally, the device has a low power consumption and balanced propagation delays, which contribute to its efficient performance. The inputs are designed to tolerate up to 5.5V, regardless of the operating voltage, which provides additional flexibility in mixed voltage systems.

With its advanced features, the 74VHC373 from STMicroelectronics is an ideal choice for applications that require high-speed data storage, such as computers, communication systems, and sophisticated industrial controls. Its robust design ensures reliable operation in the most demanding environments.
