Product Overview: M74HCT373RM13TR from STMicroelectronics

The M74HCT373RM13TR is a high-speed CMOS Octal D-type Transparent Latch manufactured by STMicroelectronics. This integrated circuit is designed to ensure optimal performance in a wide range of applications, particularly where the need for a temporary storage of data is essential. It is part of the HCT family, which means it combines the high noise immunity of CMOS with the low power consumption of TTL, making it a versatile choice for interfacing with TTL logic levels.

This device comes in a robust and compact surface-mount package, specifically the SO-20 package, which is suitable for automated assembly processes and space-constrained applications. The M74HCT373RM13TR has the capability to latch eight bits of data, with each latch having a 3-state output. This feature allows for bus-oriented applications, providing a high degree of flexibility in system design.

The transparent latch means that when the Latch Enable (LE) input is high, the Q outputs follow the data (D) inputs. However, when LE is taken low, the data that was present at the D inputs at the time the transition occurred is retained at the Q outputs until LE is returned high. Additionally, the Output Enable (OE) input can be used to place the eight outputs in either a normal logic state or a high-impedance state. Thus, the outputs can be disconnected from the bus, avoiding potential conflicts.

Key features of the M74HCT373RM13TR include its compatibility with JEDEC standard no. 7A requirements, ensuring reliability in meeting industry standards. It operates with a power supply range of 4.5V to 5.5V, which is typical for 5V logic level systems. This device also boasts a high noise immunity characteristic of CMOS technology and a low power consumption that is comparable to TTL logic.

The M74HCT373RM13TR is ideal for applications in data storage, data multiplexing, and as a buffer or line driver in digital systems. Its combination of speed, low power, and robustness makes it a smart choice for designers looking to optimize their digital logic operations.
