PI74FCT162H245T

Pericom Semiconductor's PI74FCT series of logic circuits are produced using the Company's advanced 0.6 micron CMOS technology, achieving industry leading speed grades.

The PI74FCT16245T, PI74FCT162245T, and PI74FCT162H245T are 16-bit bidirectional transceivers designed for asynchronous two-way communication between data buses. The direction control input pin (xDIR) determines the direction of data flow through the bidirectional transceiver. The Direction and Ouput Enable controls are designed to operate PI74FCT16245T, PI74FCT162245T, and PI74FCT162H245T  as either two independent 8-bit transceivers or one 16-bit transceiver. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in HIGH 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.

The PI74FCT162H245T has "Bus Hold" which retains the input's last state whenever the input goes to high-impedance preventing "floating" inputs and eliminating the need for pull-up/down resistors.
