Description
Pericom Semiconductor’s PI4ULS3V16 is a 16-bit (dual-octal)
non-inverting bus transceiver with two separate supply rails.
A port (V
3.6V. This arrangement permits universal bidirectional translation
of differential signal levels over the voltage ranges.
PI4ULS3V16 is designed for asynchronous communication
between data buses. Data is transmitted from the A bus to the B
bus, or vice versa, without direction control. All A
tri-stated when data is coming from both directions at the same
time. The output-enable (OE) input is used to disable outputs so
buses are isolated.
The control pins,

To ensure the high-impedance state during power-up or power-
down, the output-enable (OE) input should be tied to V
