TCA9543ADR

Texas Instruments · Signal Switches, Multiplexers, Decoders · SOIC-14

TCA9543ADR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Address input 0; connect to VCC or ground to set device slave address.
2 A1 input Address input 1; connect to VCC or ground to set device slave address.
3 RESET input Active-low reset input; resets I2C state machine and deselects both channels when low.
4 INT0 input Active-low interrupt input 0 from channel 0 slaves; pull-up resistor to VDPU0.
5 SD0 bidirectional Serial data 0 for channel 0 I2C bus; pull-up resistor to VDPU0.
6 SC0 bidirectional Serial clock 0 for channel 0 I2C bus; pull-up resistor to VDPU0.
7 GND power_in Ground
8 INT1 input Active-low interrupt input 1 from channel 1 slaves; pull-up resistor to VDPU1.
9 SD1 bidirectional Serial data 1 for channel 1 I2C bus; pull-up resistor to VDPU1.
10 SC1 bidirectional Serial clock 1 for channel 1 I2C bus; pull-up resistor to VDPU1.
11 INT output Active-low interrupt output combining INT0 and INT1; pull-up resistor to VDPUM.
12 SCL bidirectional Serial clock line for upstream I2C master; pull-up resistor to VDPUM.
13 SDA bidirectional Serial data line for upstream I2C master; pull-up resistor to VDPUM.
14 VCC power_in Supply power voltage with operating range 1.65 V to 5.5 V.
