STMicroelectronics 74LVQ573M Octal Latch

The 74LVQ573M is a high-performance CMOS product from STMicroelectronics designed to meet the increasing demand for low-power consumption and high-speed operation in modern electronic applications. This octal latch is an essential component for systems that require the temporary storage of data. It is capable of holding eight bits of data in a 'transparent' mode, where the output reflects the input when the latch enable (LE) signal is high, or in a 'latched' mode, where the data is retained when LE is low.

The device operates at a voltage range of 2.0V to 3.6V, making it compatible with low-voltage applications and ensuring reduced power consumption without compromising speed. The 74LVQ573M is characterized for operation from -40°C to +85°C, which ensures reliable performance over a wide temperature range, suitable for industrial and automotive applications.

One of the key features of the 74LVQ573M is its bus-hold circuitry, which eliminates the need for external pull-up or pull-down resistors and simplifies board design. This feature maintains the last valid input state whenever the input goes to a high-impedance state, providing stability and reducing potential data corruption.

The 74LVQ573M comes in a 20-lead plastic SO package, making it compact and easy to integrate into various circuit designs. Its pin configuration is optimized for convenient placement in PCB layouts, which minimizes cross-talk and signal integrity issues that are vital in high-speed operations.

With its low static and dynamic power consumption, combined with high-speed data storage capabilities, the 74LVQ573M is an ideal choice for a wide range of applications, including:

• Memory address latching
• Interface and bus buffering
• Data storage and transfer systems
• Microprocessor or microcontroller extension

STMicroelectronics' commitment to quality and reliability is evident in the 74LVQ573M, making it a trustworthy and efficient solution for designers looking to enhance their digital systems with robust latching functionality.
