Pin Configuration

PI4ULS3V16, is a 16-bit dual-octal non-inverting bus transceiver with two separate supply rails A port VCCA and B port VCCB are set to operate at 1.2V to 3.6V. This arrangement permits universal bidirectional translation of differential signal levels over the voltage ranges.

The 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 AX, and BX are 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 xSEL, xOE, TEST_EN and OUT_SEL are supplied by VCCB.

To ensure the high impedance state during power-
up or power- down, the output-enable OE input should
be tied to VCC through a pull-up resistor the minimum
value of the resistor is determined by the current-sinking
capability of the driver.
