Description
Pericom Semiconductor’s 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 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 V
minimum value of the resistor is determined by the current sinking
ability of the driver.
The PI74VCX family is I/O Tolerant, allowing it to operate in
mixed 1.8V/3.6V systems.
