STMicroelectronics M74HCT573RM13TR Product Overview

The M74HCT573RM13TR is a high-speed CMOS octal latch manufactured by STMicroelectronics, designed for use in a wide range of digital applications. This integrated circuit (IC) is part of the HCT family, which means it combines the low power consumption of CMOS technology with the ability to interface with TTL logic levels.

The device features eight latches with 3-state outputs for bus organized systems. Each latch is D-type and is capable of storing the state of each data input that is present, one setup time prior to the LOW-to-HIGH transition of the clock input. The flip-flop will store a HIGH or LOW state depending on the state of the data input at the time when the transition occurs.

The 3-state outputs ensure that the IC can be directly connected to a data bus while maintaining bus line integrity by being in a high-impedance state when not actively driving the bus. This is particularly useful in multiplexed data bus applications, where data integrity is critical. The M74HCT573RM13TR outputs can drive up to 15 LSTTL loads, which provides significant versatility in interfacing with various logic families.

The M74HCT573RM13TR operates at a voltage range of 4.5V to 5.5V, making it compatible with standard 5V systems. It also provides a balanced propagation delay and transition times, which is crucial for maintaining the timing integrity of high-speed signals. The IC is offered in a surface-mount package, specifically in a TSSOP-20 package, which makes it suitable for compact PCB layouts and automated assembly processes.

Overall, the STMicroelectronics M74HCT573RM13TR octal latch is a reliable and efficient solution for temporary data storage and data bus interfacing. It is widely used in applications such as computers, data communication equipment, and control systems where high-speed and low-power operation are essential.
