TCA9617ADGKR

Texas Instruments · Signal Switches, Multiplexers, Decoders · VSSOP-8-0.65mm

TCA9617ADGKR from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCCA power_in A-side supply voltage input, operating range 0.8V to 5.5V.
2 SCLA bidirectional Open-drain I2C SCL line on A side; requires external pull-up resistor to VCCA.
3 SDAA bidirectional Open-drain I2C SDA line on A side; requires external pull-up resistor to VCCA.
4 GND power_in Supply ground and common reference voltage.
5 EN input Active-high repeater enable input with internal weak pull-up resistor to VCCB; must change state only during bus idle.
6 SDAB bidirectional Open-drain I2C SDA line on B side; requires external pull-up resistor to VCCB.
7 SCLB bidirectional Open-drain I2C SCL line on B side; requires external pull-up resistor to VCCB.
8 VCCB power_in B-side logic supply and device operating voltage, range 2.2V to 5.5V; must power up before VCCA.
