Product Description
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.
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.
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.
Active bus-hold circuitry is provided to hold unused or floating
data inputs at a valid logic level.

3.3V 16-Bit Bidirectional Transceiver
with 3-State Output
Product Features
PI74ALVCHR162245 is designed for low voltage operation
Vcc = 2.3V to 3.6V
Hysteresis on all inputs
Typical VOLP (Output Ground Bounce)
< 0.8V at VCC = 3.3V, TA = 25°C
Typical VOHV (Output VOH Undershoot)
< 2.0V at VCC = 3.3V, TA = 25°C
All output ports have equivilent 26
Ω for overshoot/
undershoot protection 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
Industrial operation at -40°C to +85°C
Packages available:
– 48-pin 240-mil wide plastic TSSOP (A)
