Description
Pericom Semiconductor’s PI74AVC164245, a 16-bit (dual-octal)
noninverting bus transceiver, contains two separate supply rails:
B port (V
at 1.2-2.5V. This arrangement permits translation from a 1.2-2.5V
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 V
a pullup resistor: the minimum value of the resistor is determined
by the current-sinking capability of the driver.
