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 power-down, the output-enable (OE) input should be tied to VCC through a pullup resistor.
The PI4ULS3V16 is a 16‑bit (dual‑octal) non‑inverting bus transceiver designed for low‑voltage operation (1.2 V to 3.6 V). It provides universal bidirectional level shifting without direction control, independent transition of each bit, and a 12 mA drive capability. The device includes ESD protection up to 2000 V HBM and 200 V MM, and latch‑up performance exceeding 100 mA.
The datasheet details maximum ratings, pin configurations for TSSOP and TQFN packages, electrical and timing characteristics, recommended land patterns, and ordering information. It is intended for designers needing voltage translation, bus relay, or other high‑speed signaling applications.
