STMicroelectronics M74HCT573TTR Octal Transparent Latch

The M74HCT573TTR from STMicroelectronics is a high-performance CMOS octal transparent latch designed to operate in a wide range of applications, from industrial to consumer electronics. This integrated circuit is part of the HCT family, which means it is compatible with TTL logic levels and can be directly interfaced with MOS and bipolar circuits.

Featuring a robust design, the M74HCT573TTR provides latch function for eight data lines, each with 3-state non-inverting outputs. The transparent latches hold data when the Latch Enable (LE) input is high, and pass data when LE is low, offering a flexible way to manage data flow in a system. The 3-state outputs ensure that additional latches or drivers can be connected to a common bus without conflict.

The device is characterized for operation from -55°C to 125°C, making it suitable for use in environments with extreme temperature conditions. It comes in a TSSOP package, which is ideal for space-constrained applications, and the surface-mount design allows for more compact and efficient PCB layouts.

Key Features:

• High-Speed CMOS Logic
• Octal D-type transparent latch with 3-state outputs
• Direct LSTTL input logic compatibility; VIL=0.8V (max), VIH=2V (min)
• CMOS input compatibility: Il ≤ 1µA at VOL, VOH
• Power down protection on inputs and outputs
• Support for low power operation with a typical quiescent current of 4µA
• Wide operating temperature range: -55°C to 125°C
• Available in TSSOP48 package for reduced space requirements

The M74HCT573TTR is designed for use in applications that require high-speed, reliable data retention and interfacing. It is commonly used in data buffering in computers, communication systems, and other digital systems where a temporary storage of data is required. The device's compatibility with a wide range of logic families makes it a versatile choice for designers looking to create flexible and resilient electronic systems.

Overall, the M74HCT573TTR is a testament to STMicroelectronics' commitment to providing high-quality, reliable components that meet the evolving needs of modern electronic designs.
