PI4ULS3V504 280Mb/s Bidirectional Level Translator for Push-Pull Applications Features Description 0.85V to 2.7V on A Port and 1.35V to 3.6V on B Port The PI4ULS3V504 is a 4-bit configurable, dual-supply VCCA may be Greater than, Equal to, or Less than VCCB autosensing bidirectional level translator that does not require High-Speed with 280 Mb/s Guaranteed Date Rate a direction control pin. The B and A ports are designed to 30 pF Capacitive Drive Capability track two different power supply rails, VCCB and VCCA Low Bit-to-Bit Skew respectively. Overvoltage Tolerant Enable and I/O Pins The PI4ULS3V504 offers the feature that the values of the Non-Preferential Power-Up Sequencing VCCB and VCCA supplies are independent. Design flexibility Power-Off Protection is maximized because VCCA can be set to a value either Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) greater than or less than the VCCB supply. Halogen and Antimony Free. Green Device (Note 3) For automotive applications requiring specific change The PI4ULS3V504 has high-output current capability, which control (i.e. parts qualified to AEC-Q100/101/200, PPAP allows the translator to drive high-capacitive loads such as capable, and manufactured in IATF 16949 certified most high-frequency EMI filters. Another feature of the facilities), please contact us or your local Diodes PI4ULS3V504 is that each An and Bn channel can function as representative. either an input or an output.
