ON Semiconductor 74ALVC162245T: 16-Bit Transceiver with 3-State Outputs

The 74ALVC162245T from ON Semiconductor is a high-performance, 16-bit transceiver designed for asynchronous communication between data buses. The device is capable of transferring data from the A bus to the B bus and vice versa, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to disable the device so that the buses are effectively isolated.

One of the key features of the 74ALVC162245T is its low-voltage operation, which ranges from 1.65V to 3.6V. This makes it suitable for interfacing with low-voltage logic, which is commonly used in modern microprocessors and microcontrollers. The device also supports 5V tolerant inputs, which allows it to be used in mixed-voltage systems without the need for additional level shifting.

The transceiver's high-speed performance is characterized by a typical propagation delay of only 3.8ns, ensuring fast data transfer between buses. Moreover, the 74ALVC162245T boasts a robust ESD protection, which safeguards the device against electrostatic discharge, enhancing its reliability and longevity in various applications.

Designed with a bus-hold feature, the inputs retain the last known state without the need for external pull-up or pull-down resistors, simplifying the design and reducing component count. The device is equipped with 3-state outputs, which allow for connection to a common bus, providing a high-impedance state when not in use.

The 74ALVC162245T comes in a TSSOP (Thin Shrink Small Outline Package) form factor, which is conducive for space-constrained applications. Its compact size and the fact that it is offered in a RoHS-compliant package make it an environmentally friendly choice for hardware designers.

This transceiver is perfect for applications that require high-speed data transfer or interfacing between different voltage domains, such as computing, networking, and telecommunications. The 74ALVC162245T's combination of features ensures that it can meet the demands of a wide range of high-performance digital systems.
