The Texas Instruments PCA9546APW is a versatile 4-channel I2C and SMBus switch featuring a reset function and voltage translation capabilities. It allows for bidirectional translation between various bus voltages, including 1.8V, 2.5V, 3.3V, and 5V, enabling communication between different logic levels without additional protection circuitry.
This switch operates over a power supply voltage range of 2.3V to 5.5V and supports clock frequencies up to 400kHz. It features an active-low reset input for recovering from bus issues and an internal power-on reset function. The device is available in a 16-TSSOP package, suitable for surface mount applications.
Key features include low standby current, 5.5V tolerant inputs, and support for hot insertion. The PCA9546APW is designed to prevent glitches during power-up and offers excellent ESD protection, exceeding JESD 22 standards. Its ability to select individual channels or combinations via the I2C bus makes it ideal for complex interface management.
