PI74ALVTC16245A - 16-Bit Bus Transceiver from Diodes Incorporated

The PI74ALVTC16245A is a high-performance, 16-bit non-inverting bus transceiver designed by Diodes Incorporated. This device is part of the advanced low-voltage technology class (ALVTC), which provides a perfect balance between speed and power consumption, making it an ideal choice for interfacing with high-speed communication buses in energy-conscious applications.

The PI74ALVTC16245A operates from a 2.5V to 3.3V power supply, ensuring compatibility with modern low-voltage logic systems. With its wide voltage range, it can easily be integrated into mixed-voltage environments, facilitating communication between devices operating at different logic levels.

This bus transceiver features 16 bidirectional data lines, divided into two 8-bit bus ports (A and B). Each port is equipped with separate input and output control signals, allowing for flexible direction control. The device supports bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors and simplifies board design.

One of the key attributes of the PI74ALVTC16245A is its high drive capability, which can source or sink 24 mA at 3.3V. This feature enables the device to drive heavily loaded buses with minimal signal distortion. Additionally, the bus transceiver boasts low ON resistance, contributing to its high-speed operation.

The PI74ALVTC16245A comes in a variety of packaging options, including the 48-pin Thin Shrink Small Outline Package (TSSOP) and 48-pin Very Thin Quad Flat Pack (VQFP). These compact packages are ideal for space-constrained applications and ensure efficient use of PCB real estate.

With its robust design, the PI74ALVTC16245A is characterized for operation from -40°C to +85°C, making it suitable for industrial temperature ranges. It is also fully specified for partial power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

In summary, the PI74ALVTC16245A from Diodes Incorporated is a versatile, high-speed bus transceiver that offers an excellent feature set for applications requiring efficient data transfer and interfacing between different logic levels in a low-voltage environment.
