STMicroelectronics 74LVQ573MTR Octal Latch

The 74LVQ573MTR from STMicroelectronics is a high-performance CMOS octal latch designed to address the requirements of high-speed memory buffering with low-power consumption. This integrated circuit is a part of the LVQ family and is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working memory in a wide array of applications ranging from personal computers to industrial control systems.

With its octal D-type transparent latch structure, the 74LVQ573MTR features eight latches with three-state outputs. The device operates with a 3.3V power supply, making it compatible with TTL levels while ensuring reduced power consumption compared to traditional 5V devices. The inputs and outputs are equipped with protection against static discharge, offering robustness and reliability in operation.

The latch comes in a 20-lead TSSOP (Thin Shrink Small Outline Package) that is optimized for reduced space on printed circuit boards. This package makes the 74LVQ573MTR ideal for applications where space is at a premium and where high-speed data storage and transfer are critical.

Key features of the 74LVQ573MTR include:

• High-speed operation: The device is capable of handling clock frequencies up to 160 MHz, making it suitable for high-performance systems.
• Low power consumption: Operating at 3.3V, the 74LVQ573MTR is designed for low-power applications, helping to extend battery life in portable devices.
• Bus hold data inputs: These inputs eliminate the need for external pull-up resistors, simplifying board design and reducing component count.
• Three-state outputs: This feature allows for connection to a common bus, facilitating data transfer without interference.
• Improved output drive capability: The device can drive 24 mA at the outputs, ensuring good signal integrity even in demanding applications.

Whether you're designing a sophisticated computer system or a simple data buffer, the 74LVQ573MTR by STMicroelectronics offers a combination of high-speed performance, low-power operation, and compact packaging to meet your design needs.
