Block Diagram

Pericom Semiconductor’s PI74FCT16245T and PI74FCT162245T are 16-bit bidirectional transceivers designed for asynchronous twoway communication between data buses. The direction control input pin xDIR determines the direction of data Àow through the bidirectional transceiver. The Direction and Ouput Enable controls are designed to operate these devices as either two independent 8bit transceivers or one 16-bit transceiver. The output enable OE input, when HIGH, disables both A and B ports by placing them in Hi-Z condition.

The PI74FCT16245T output buffers are designed with a power off disable allowing “live insertion” of boards when used as backplane drivers.

The PI74FCT162245T has ±24mA balanced output drivers. It is designed with current limiting resistors at its outputs to control the output edge rate resulting in lower ground bounce and undershoot. This eliminates the need for external terminating resistors for most interface applications.
