Translator can drive high capacitive loads like most EMI filters

05-02-2021 | Mouser Electronics | Semiconductors

Diodes Incorporated PI4ULS3V304AQ Automotive Qualified Translator, available now from Mouser, is a 4-bit configurable dual-supply autosensing bidirectional level translator.


The device does not need a direction control pin. The B and A ports are intended to track two different power supply rails, VCCB and VCCA. The VCCA can be set to an independent value. Design either greater than or less than the VCCB supply, the device offers high output current capability that enables the translator to drive high capacitive loads like most high-frequency EMI filters.


Another feature of the device is that each An and Bn channel can function as either an input or an output. An Output Enable (EN) input is offered to decrease the power consumption. The EN pin is employed to disable I/O ports by putting them in three-state which noticeably diminishes the supply current. The device is capable of 2kV System-Level ESD.


Typical applications include automotive, mobile phones, PDAs, and other portable devices.
