ON Semiconductor MC74VCXH16240DT Product Overview

The ON Semiconductor MC74VCXH16240DT is a high-performance, 16-bit buffer and line driver designed for use in systems that require low voltage and low power consumption without sacrificing speed and performance. This integrated circuit is part of the VCXH family, which is known for its versatility in voltage interfacing and level shifting in multi-voltage systems.

Constructed with advanced CMOS technology, the MC74VCXH16240DT operates at a nominal voltage of 3.3V, but it is tolerant to 5V inputs, making it highly suitable for mixed-voltage environments. It is designed to have a high drive current of ±24mA at the outputs, ensuring strong signal integrity and the ability to drive heavy loads.

Featuring a 16-bit wide format, this buffer and line driver can be used to increase the drive strength of bus lines or to isolate the bus capacitance, allowing for improved system performance. Its high-speed propagation delay and output transition time are optimized for high-speed signal processing, which is essential for modern digital applications.

The MC74VCXH16240DT is equipped with multiple features that enhance its functionality and reliability. It includes bus-hold circuitry on all inputs, which eliminates the need for external pull-up or pull-down resistors and ensures that the inputs remain at a valid logic level when open. Additionally, the device offers power-off high impedance inputs and outputs, which prevent unintended signal propagation and reduce power consumption when the device is turned off.

With its low on-resistance, the MC74VCXH16240DT ensures minimal signal distortion and reduced power dissipation. The device is also characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

The MC74VCXH16240DT is packaged in a TSSOP-48 (Thin Shrink Small Outline Package), which provides a space-saving footprint while allowing for efficient thermal performance and ease of PCB layout. This makes it an ideal choice for a broad range of applications, including communication systems, data processing, and high-speed interfacing in both industrial and consumer electronics.

Overall, the ON Semiconductor MC74VCXH16240DT is a robust and versatile component that offers a blend of speed, power efficiency, and reliability, making it a valuable addition to any high-performance digital system.
