ON Semiconductor MC74LCX16373DT Low-Voltage CMOS 16-Bit Transparent Latch

The ON Semiconductor MC74LCX16373DT is a high-performance, 16-bit transparent latch designed for use in systems that require low power consumption without sacrificing speed and performance. This integrated circuit is part of the LCX family of products, which are known for their advanced features and reliability in a variety of applications.

Constructed with advanced silicon-gate CMOS technology, the MC74LCX16373DT offers a robust solution for high-speed operation while maintaining a low power draw. It operates at a voltage range of 2.3V to 3.6V, making it ideal for interfacing with both 3.3V and 2.5V logic levels. This flexibility ensures that the device can be used in a wide range of applications, from consumer electronics to industrial control systems.

One of the key features of this product is its transparent latch functionality. Each latch has a separate output-enable (OE) input and latch-enable (LE) input. When LE is high, the flip-flops take data from the D inputs, which is then reflected on the outputs when OE is low. This allows for seamless data flow and storage, which is crucial for data integrity in complex systems.

The MC74LCX16373DT also boasts a 5V tolerant input, which enables the device to be used in mixed-voltage environments without the need for additional level shifters. This is particularly useful when upgrading legacy systems that operate at higher voltages.

For signal integrity, the device features built-in bus hold, which helps maintain the last active state on the data lines if they become disconnected or are left floating. This feature minimizes potential data corruption and ensures stable operation.

The device is packaged in a TSSOP-48 (Thin Shrink Small Outline Package), which offers a compact footprint suitable for space-constrained applications. Its surface-mount design is compatible with modern PCB assembly processes, facilitating easy integration into system designs.

In summary, the ON Semiconductor MC74LCX16373DT is a versatile and reliable choice for designers looking for a high-quality transparent latch. With its low-voltage operation, 5V tolerant inputs, and bus hold feature, it provides a seamless and stable performance for a variety of digital applications.
