PI74VCX16245  
2.5V 16-Bit Bidirectional Transceiver  
with 3-State Outputs  
Product Features  
Product Description  
• The PI74VCX family is designed for low voltage operation  
Pericom Semiconductor’s PI74VCX series of logic circuits are  
produced in the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.

• 3.6V I/O Tolerant Inputs and Outputs  
• Supports Live Insertion  
The PI74VCX16245 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  
OutputEnablecontrolsaredesignedtooperatethisdeviceaseither  
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.  
• Balanced output drive, ±24mA  
• Uses patented Noise Reduction Circuitry  
• Typical V

To ensure the high-impedance state during power up or power  
down, OE should be tied to Vcc through a pull-up resistor; the  
minimum value of the resistor is determined by the current sinking  
ability of the driver.  
• Power-Off High Impedance inputs and outputs  
• Industrial operation at –40°C to +85°C  
• Packages available:

The PI74VCX family is I/O Tolerant, allowing it to operate in  
mixed 1.8V/3.6V systems.
