Description
The PI4ULS3V501 is a 2-bit configurable dualsupply autosensing bidirectional level translator that does not require a direction control pin. The B and A ports are designed to track two different power supply rails, VCCB and VCCA respectively.
The PI4ULS3V501 offers the feature that the values of the VCCB and VCCA supplies are independent. Design flexibility is maximized because VCCA can be set to a value either greater than or less than the VCCB supply.
The PI4ULS3V501 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 PI4ULS3V501 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 power consumption. The EN pin can be used to disable both I/O ports by putting them in 3-state which significantly reduces the supply current.
PI4ULS3V501 is 2 kV System-Level ESD Capable.
