PI74ALVCHR162245  
3.3V 16-Bit Bidirectional Transceiver  
with 3-State Output  
Product Description  
Product Features  
Pericom Semiconductor’s PI74ALVCH series of logic circuits are  
produced using the Company’s advanced 0.5 micron CMOS  
technology to achieve industry-leading speed grades.  
• PI74ALVCHR162245isdesignedforlowvoltageoperation  
• Vcc=2.3Vto3.6V  
• Hysteresis on all inputs  
The PI74ALVCHR162245 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.  
• Typical VOLP (Output Ground Bounce)  
< 0.8V at V = 3.3V, TA = 25°C  
CC  
• Typical VOHV (Output VOH Undershoot)  
< 2.0V at V = 3.3V, TA = 25°C  
CC  
• All output ports have equivilent 26Ω series resistors:  
No external resistors are required  
• Bus Hold retains last active bus state during 3-state  
eliminating the need for external pull-up resistors  
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.  
• Industrial operation at -40°C to +85°C  
• Packages available:  
–48-pin240-milwideplasticTSSOP(A)  
–48-pin300-milwideplasticSSOP(V)  
Active bus-hold circuitry is provided to hold unused or floating  
data inputs at a valid logic level.
