描述 Description

The PI3CLS9606 is a 2-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation for traditional I2C-bus/SMBus applications, and 12.5 MHz 13C-bus applications. It features two 1-bit input-output ports (An and Bn), one output enable input (OE) and two supply pins (VCCA and VCCB). VCCA can be supplied at any voltage between 0.72V and 1.98V and VCCB can be supplied at any voltage between 0.72V and 1.98V. VCCA must be ≤VCCB to ensure proper operation. PI3CLS9606 can be used for both open drain as well as push- pull application which allows for level translation applications using 13C and I2C protocols.


Port A is referenced to VCCA and port B is referenced to VCCB. The active HIGH OE pin is referenced to VCCA and controllable by a signal in either VCCA or VCCB domain. A LOW level at pin OE causes the outputs to be in a high-impedance OFF-state. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is in powered down.
