Description
PI4ULS3V08M, is a 8-bit (octal) non-inverting bus
transceiver with two separate supply rails: A port (V
and B port (V
arrangement permits universal bidirectional translation of
differential signal levels over the voltage ranges.
The PI4ULS3V08M 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, OEx, TEST_EN and OUT_SEL are supplied by
V
To ensure the high impedance state during power-up or power-
down, the output-enable (OEx) 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.
