STMicroelectronics 74LCX373MTR Octal Transparent Latch

The 74LCX373MTR is a high-performance CMOS product from STMicroelectronics, designed to meet the escalating needs of advanced 3.3V systems. This octal transparent latch with 3-state outputs is part of the LCX family, which offers 5V tolerant inputs and outputs for interfacing with 5V systems, making it a versatile choice for mixed-voltage applications.

Featuring eight latches with three-state outputs, this device is ideal for storing data and can be used in a wide range of applications, from temporary data storage to interfacing and system resource allocation. The transparent latches allow data to flow from the inputs to the outputs while the Latch Enable (LE) input is high, and capture data when LE goes low. The Output Enable (OE) bar controls the three-state outputs and ensures that the outputs are in a high-impedance state when OE is high.

Designed for low-voltage operation, the 74LCX373MTR operates at a voltage range of 2.3V to 3.6V, which not only reduces power consumption but also minimizes the risk of overheating, making it a reliable choice for power-sensitive designs. Additionally, the device supports a high drive capability of ±24mA at the outputs, providing excellent signal integrity and reducing the need for additional buffering components.

The 74LCX373MTR is characterized for operation from -40°C to +85°C, ensuring robust performance over a wide temperature range. The device comes in a TSSOP-20 package, which is ideal for space-constrained applications due to its small footprint.

STMicroelectronics has designed the 74LCX373MTR with advanced circuitry to provide a fast propagation delay and reduced noise generation, thereby enhancing the overall performance of the system it is integrated into. Furthermore, the device is fully specified for partial power-down applications using Ioff, which helps in preventing damaging current backflow through the device when it is powered down.

The 74LCX373MTR is a testament to STMicroelectronics' commitment to providing high-quality, innovative semiconductor solutions that cater to the evolving demands of modern electronic systems.
