Diodes Incorporated PI74AVC164245A Logic Interface

The Diodes Incorporated PI74AVC164245A is a high-performance, 16-bit bidirectional transceiver designed to interface with 1.8V, 2.5V, or 3.3V buses. This versatile component is part of the AVC family, which is renowned for its low-voltage operation and low noise levels, making it an ideal choice for a range of applications that require efficient data transfer between two buses of different voltage levels.

With its wide bus-interface capability, the PI74AVC164245A can be used in various applications such as data communication, telecommunication systems, and within computing environments. Its bidirectional data path allows for seamless communication in either direction, from A to B or B to A, depending on the direction control (DIR) input signal. The output enable (OE) input allows users to place the output in high-impedance mode, which is particularly useful in multiplexed bus applications where data integrity is crucial.

The PI74AVC164245A supports bus hold on data inputs, eliminating the need for external pull-up or pull-down resistors and simplifying board design. This feature also helps to maintain last known states on the bus during power down or when inputs are left floating. The device is designed to prevent latch-up and includes over-voltage tolerance on inputs to enhance robustness and reliability in demanding environments.

Key features of the PI74AVC164245A include:

• Operates from 1.65V to 3.6V V<sub>CC supply range
• High-speed data transfer rates
• Low quiescent current, making it suitable for battery-operated devices
• ESD protection exceeds JESD 22
• Industrial operating temperature range: -40°C to +85°C
• Available in a variety of packaging options, including TSSOP and QSOP

The PI74AVC164245A is available in lead-free, RoHS-compliant packaging, reflecting Diodes Incorporated's commitment to environmental sustainability. Whether you're developing high-speed data interfaces or expanding the capabilities of lower voltage systems, this transceiver is designed to provide a reliable and efficient solution for your digital logic needs.
