PI74LPT16245

3.3V 16-BIT BIDIRECTIONAL TRANSCEIVER

PI74LPT16245

Fast CMOS 3.3V 16-Bit

Bidirectional Transceiver

Product Features

Product Description

•

CompatiblewithLCX™andLVT™familiesofproducts

Pericom Semiconductor’s PI74LPT series of logic circuits are pro-

duced in the Company’s advanced 0.6 micron CMOS technology,

achieving industry leading speed grades.

•

Supports 5V Tolerant Mixed Signal Mode Operation

– Input can be 3V or 5V

– Output can be 3V or connected to 5V bus

The PI74LPT16245 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 this device 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.

•

Advanced Low Power CMOS Operation

Excellent output drive capability:

Balanced drives (24 mA sink and source)

•

Pin compatible with industry standard double-density

pinouts

•

Low ground bounce outputs

Hysteresis on all inputs

ThePI74LPT16245canbedrivenfromeither3.3Vor5.0Vdevices

allowing this device to be used as a translator in a mixed

3.3/5.0V system.

Industrial operating temperature range: –40°C to +85°C

Multiple center pins and distributed Vcc/GND pins

minimize switching noise
