PCA9546ARGVR Description

Short technical summary and product information.

The PCA9546ARGVR from Texas Instruments is a versatile 4-channel I2C and SMBus switch designed for interface applications. It allows for bidirectional translation between different voltage levels, supporting buses from 1.8V up to 5V, with an operating power supply range of 2.3V to 5.5V. The device features an active-low reset input for recovery from bus lock-ups and an internal power-on reset function.

 

This switch is compatible with I2C and SMBus protocols and operates at clock frequencies up to 400 kHz. It offers features such as channel selection via the I2C bus, no glitch on power-up, and support for hot insertion. The PCA9546ARGVR is housed in a compact 16-VQFN (4x4) package, suitable for surface mounting.

 

Key electrical characteristics include 5.5V tolerant inputs and latch-up performance exceeding 100 mA. ESD protection is provided, rated at 2000V for the Human-Body Model and 1000V for the Charged-Device Model. The operating temperature range is from -40°C to 85°C, making it suitable for a variety of environmental conditions.
