PI74FCT162245TAE

Buffers, Drivers, Receivers, Transceivers Overview

The PI74FCT162245TAE is a Fast CMOS 16-bit bidirectional transceiver designed for asynchronous two-way communication between data buses. It operates at VCC = 5V ±10% and features balanced output drivers with ±24mA current capability. The device includes internal current limiting resistors to control edge rates, reducing ground bounce and undershoot. It supports configurations as two independent 8-bit transceivers or one 16-bit unit via direction control inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific speed grade suffix (Blank, A, or C) against the required propagation delay specifications. Confirm the package type corresponds to the 'A' code for 48-pin TSSOP. Ensure the 'E' suffix indicates Pb-free and Green compliance if environmental standards are mandatory for the application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when low ground bounce is critical due to its balanced ±24mA drivers and internal series resistors. It is suitable for applications requiring live insertion capabilities. Compare against the PI74FCT16245T if higher asymmetric drive currents are needed instead of balanced performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Pericom FCT series of Fast CMOS logic devices manufactured by Diodes Incorporated. It is functionally related to the PI74FCT16245T but differs in output driver characteristics, offering balanced rather than high-asymmetric drive currents for reduced noise.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the PI74FCT162245T handle power-off conditions?

The device features power off disable outputs that place ports in a High-Z state when VCC is removed, permitting live insertion of boards without bus contention.

What is the typical output ground bounce voltage for this device?

The typical Output Ground Bounce (VOLP) is less than 0.6V at VCC = 5V and TA = 25°C, which is lower than standard variants due to internal current limiting resistors.
