Fast, Low Noise Cmos 16-bit Bidirectional Transceivers

Pericom Semiconductors PI74FCT series of Logic circuits are pro- duced in the Companys advanced 0.6 micron CMOS technology, achieving industry leading speed grades. The PI74FCT162Q245T is a 16-bit bidirectional transceiver 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 Output Enable controls are designed to operate these devices 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 PI74FCT162Q245T is designed with current limiting resistors at its outputs to control the output edge rate resulting in lower ground bounce and undershoot. This device features a typical output impedance of 35, eliminating the need for external terminating resistors for most bus Interface applications. This noise suppression benefit is designated by the letter Q (for quiet) in the part number. The PI74FCT162Q245T also features Bus Hold which retains the inputs last state whenever the input goes to high-impedance preventing floating inputs and eliminating the need for pullup/ down resistors.
