PI74FCT162245MT

16-BIT BIDIRECTIONAL TRANSCEIVERS

PI74FCT162245MT

Fast CMOS 16-Bit

Heavy Load

Bidirectional Transceivers

Product Description:

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 PI74FCT162245MT is a 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 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. It is

designed specifically for heavy load applications.

Hysteresis on all inputs

Balanced output drivers: ±24 mA

Reduced system switching noise

Typical V^OLP(Output Ground Bounce) < 0.6V

atVCC =5V,TA =25°C

Packagesavailable:

The PI74FCT162245MT has ±24 mA 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.
