Frequently Asked Questions
What is the maximum number of I2C channels the TCA9548ARGER supports?
The TCA9548ARGER supports up to 8 independent I2C channels. Each channel can be individually enabled or disabled via the control register, allowing up to 8 separate I2C bus segments to share a single master without address conflicts.
What is the operating supply voltage range for the TCA9548ARGER?
The TCA9548ARGER operates from a supply voltage of 1.65V to 5.5V, making it suitable for both 3.3V and 5V I2C systems. This wide range provides flexibility for interfacing devices with different logic levels in mixed-voltage designs.
How does the reset pin function on the TCA9548ARGER?
The TCA9548ARGER includes an active-low reset pin (RESET#) that, when asserted, disables all channels and sets the control register to zero. This feature helps recover from bus lock-up conditions caused by stuck I2C devices, improving overall system reliability.
What package type is the TCA9548ARGER and what are its dimensions?
The TCA9548ARGER comes in a VQFN-24 (24-pin Very Thin Quad Flat No-Lead) package with a 4mm x 4mm body footprint. This compact package is ideal for space-constrained PCB designs in portable and embedded applications.
Can the TCA9548ARGER be used to connect I2C sensors with duplicate addresses?
Yes, the TCA9548ARGER is specifically designed to solve the problem of duplicate I2C addresses. By enabling only one channel at a time, the master can communicate with multiple identical sensors or devices that share the same 7-bit I2C address without conflict.
