PI4ULS3V504 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 PI4ULS3V504 is a 4-bit configurable dual-supply Port autosensing bidirectional level translator that does not require a direction control pin. The B and A ports are VCCA may be greater than, equal to, or less than designed to track two different power supply rails, VCCB VCCB and VCCA respectively. High-Speed with 280 Mb/s Guaranteed Date Rate The PI4ULS3V504 offers the feature that the values of 30 pF Capacitive Drive Capability the VCCB and VCCA supplies are independent. Design Low Bit-to-Bit Skew flexibility is maximized because VCCA can be set to a Overvoltage Tolerant Enable and I/O Pins value either greater than or less than the VCCB supply. Non-preferential Power-Up Sequencing The PI4ULS3V504 has high output current capability, Power-Off Protection which allows the translator to drive high capacitive loads Package: UQFN1.7x2.0-12L such as most high frequency EMI filters. Another feature of the PI4ULS3V504 is that each An and Bn channel can function as either an input or an output. An Output Enable (EN) input is available to reduce the Applications power consumption. The EN pin can be used to disable Mobile Phones, PDAs both I/O ports by putting them in 3-state which Other Portable Devices significantly reduces the supply current. The PI4ULS3V504 is 2 kV System-Level ESD Capable. Pin Description Pin Pin Type Description Pin Configuration No. Name A-port supply voltage.0.85V VccA 1 Power VCCA 2.7 V Input/output A.
