Description
Pericom Semiconductor’s PI74ALVCH16245 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 Hi-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.
Features
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
Bus Hold retains last active bus state during 3-STATE,
eliminating the need for external pullup resistors
Industrial operation at –40°C to +85°C
Packaging:
– 48-pin 240-mil wide plastic TSSOP (A)
