ON Semiconductor 74LCX16373MEA Low Voltage 16-Bit Transparent Latch

The 74LCX16373MEA from ON Semiconductor is a high-performance, low-voltage 16-bit transparent latch designed with the modern system integration needs in mind. This integrated circuit (IC) is part of the LCX family, which is known for its devices that feature a 5V tolerant input for interfacing with 5V systems while maintaining the low power consumption and high-speed operation of a 3.3V system.

Constructed with advanced silicon-gate CMOS technology, the 74LCX16373MEA offers significant power and speed enhancements over standard logic ICs. It is optimized for use in high noise environments, where signal integrity can be compromised. The latch is equipped with multiple features that make it a robust and flexible component for a wide range of applications, including memory address latching, data storage, and input/output buffering.

Key features of the 74LCX16373MEA include:

• Wide Operating Voltage Range: The device operates at a voltage range of 2.0V to 3.6V, making it suitable for low-voltage applications.
• 5V Tolerant Inputs: Inputs can tolerate voltages up to 5V, even when the device is powered off, providing interface compatibility with older 5V systems.
• High-Speed Operation: It boasts a high-speed operation with a typical propagation delay of only 3.8ns at 3.3V, ensuring swift data handling and processing.
• Low Power Consumption: The IC features a low quiescent current, significantly reducing power usage in standby mode.
• Bus-Hold Data Inputs: The bus-hold feature eliminates the need for external pull-up or pull-down resistors, saving board space and component costs.
• Power-Off Protection: All inputs and outputs have power-off protection, which prevents any damaging backflow current through the device when it is powered down.

The 74LCX16373MEA comes in a 48-lead SSOP package that is both space-saving and convenient for automated assembly processes. Its performance and reliability make it an excellent choice for designers looking to incorporate a transparent latch into their systems, where maintaining data integrity and minimizing power draw are critical.

With the 74LCX16373MEA, ON Semiconductor continues its commitment to providing innovative, high-quality components for the ever-evolving electronics industry.
