STMicroelectronics 74VCXH16244TTR Low Voltage 16-Bit Buffer/Line Driver

The 74VCXH16244TTR from STMicroelectronics is a high-performance, low-voltage 16-bit buffer and line driver designed to operate at 3.3V or 2.5V while providing 5V tolerant I/Os. This versatile device is ideal for driving bus lines or buffer memory address registers with its robust output drivers that can sink/source 24 mA at 3.3V. With an emphasis on high-speed signal propagation, the 74VCXH16244TTR is perfect for interfacing with high-speed microprocessors and can significantly improve the performance of bus operations in a wide array of applications.

Constructed with advanced multiplexed CMOS technology, the 74VCXH16244TTR combines high-speed operation with the true CMOS low power consumption. It features a wide operating voltage range of 1.65V to 3.6V, making it versatile for various low voltage applications. The device also offers power-down high impedance inputs and outputs, ensuring minimal power consumption when not in active use.

The 74VCXH16244TTR is packaged in a TSSOP48 (Thin Shrink Small Outline Package) that is optimized for reduced space on PCBs. This package provides a reliable connection to the circuit board and is suitable for wave or reflow soldering, contributing to ease of manufacturing and assembly. The device is also characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide temperature range, making it suitable for industrial and automotive applications.

Key features of the 74VCXH16244TTR include its bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, and its low noise figure of 1.0V (max). Additionally, the device is designed with an optimized pin-out for improved signal integrity, and it is fully specified for partial power-down applications using Ioff. The Ioff circuitry ensures that the device's outputs are disabled when it is powered down, preventing damaging current backflow through the device.

Overall, the 74VCXH16244TTR is a reliable and efficient solution for systems that require high-speed data transfer and buffering with the assurance of low power consumption and 5V tolerant interfaces.
