Description
Pericom Semiconductor’s PI74AVC164245LA, a 16-bit (dual-octal)
noninverting bus transceiver, contains two separate supply rails:
B port (V
at 1.5-2.5V. This arrangement permits translation from a 1.5-2.5V to
3.3V environment and vice versa. The control pins, OE and DIR are
controlled by V
The PI74AVC164245LA 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.
