ON Semiconductor 74VHC161284MTD - Bus Transceiver with Voltage Translation

The ON Semiconductor 74VHC161284MTD is a high-performance, low-power bus transceiver designed to facilitate voltage level translation in multi-voltage systems. This device is part of the 74VHC family, which is known for its versatility and reliability in a wide range of applications, from consumer electronics to industrial automation.

The 74VHC161284MTD features a 19-bit interface that supports bidirectional communication between two buses of different voltage levels. It can translate signals from a lower voltage (1.2V to 3.6V) up to a higher voltage (3.0V to 5.5V), making it an ideal solution for interfacing between modern low-voltage components and legacy 5V systems.

With its bus-hold circuitry, the 74VHC161284MTD maintains the last active state during moments when the data inputs are not actively driven, ensuring signal integrity and reducing the need for external pull-up or pull-down resistors. This feature simplifies PCB design and helps to save space and cost in your application.

The device is housed in a 56-lead TSSOP package (MTD suffix), which is optimized for reduced space and weight in board designs. Its package is also RoHS compliant, adhering to environmental standards and regulations.

ON Semiconductor's commitment to quality ensures that the 74VHC161284MTD provides high-speed operation with a typical propagation delay of only 5.5ns. This makes it suitable for high-frequency applications where fast data transfer is crucial. Additionally, the device has a balanced output drive with current limiting resistors, which helps to reduce the effects of simultaneous switching outputs (SSO) and minimizes signal distortion.

Overall, the 74VHC161284MTD is a robust and flexible solution for systems requiring voltage level translation. Its high-speed performance, integrated bus-hold feature, and space-saving design make it a valuable component for modern electronic designs that need to bridge the gap between different voltage domains.
