Description
Pericom Semiconductor’s PI74AVC164245, a 16-bit (dual-octal) noninverting bus transceiver, contains two separate supply rails: B port (VCCB), set at 3.3V, and A port (VCCA), set to operate at 1.8-2.5V. This arrangement permits translation from a 1.8-2.5V to 3.3V environment and vice versa.
The PI74AVC164245 is designed for asynchronous communication between data buses.
To ensure the high impedance state during power up or power down, the output-enable (OE) input should be tied to VCC through a pullup resistor: the minimum value of the resistor is determined by the current-sinking capability of the driver.
