PI4ULS3V502 280Mb/s Bi-directional Level Translator for Push-Pull Applications Features Description 0.85V to 2.7V on A Port and 1.35V to 3.6V on B The PI4ULS3V502 is a 2-bit configurable dual- Port supply autosensing bidirectional level translator that VCCA may be greater than, equal to, or less than does not require a direction control pin. The B and A VCCB ports are designed to track two different power supply High-Speed with 280 Mb/s Guaranteed Date Rate rails, VCCB and VCCA respectively. 30 pF Capacitive Drive Capability The PI4ULS3V502 offers the feature that the values Low Bit-to-Bit Skew of the VCCB and VCCA supplies are independent. Overvoltage Tolerant Enable and I/O Pins Design flexibility is maximized because VCCA can be Non-preferential Power-Up Sequencing set to a value either greater than or less than the VCCB Power-Off Protection supply. Package: UDFN1.2x1.6-8L The PI4ULS3V502 has high output current capability, which allows the translator to drive high capacitive loads such as most high frequency EMI filters. Another feature of the PI4ULS3V502 is that each An and Bn channel can function as either an input or an Applications output. Mobile Phones, PDAs An Output Enable (EN) input is available to reduce Other Portable Devices the power consumption. The EN pin can be used to disable both I/O ports by putting them in 3-state which Pin Configuration significantly reduces the supply current. PI4ULS3V502 is 2 kV System-Level ESD Capable.
