Description
Pericom Semiconductor's 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. 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 powerdown, the output-enable (OE) input should be tied to VCC through a pullup resistor.

Note: 1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. This value is limited to 3.6V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. 4. Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
