TCA9801DGKR

Texas Instruments · Translators, Level Shifters · VSSOP-8-0.65mm

TCA9801DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 VCCA power_in A-side supply voltage with operating range 0.8 V to 3.6 V.
2 SCLA bidirectional I2C serial clock A-side; open-drain bidirectional requiring external pull-up resistor to VCCA.
3 SDAA bidirectional I2C serial data A-side; open-drain bidirectional requiring external pull-up resistor to VCCA.
4 GND power_in Ground reference.
5 EN input Active-high repeater enable input with internal pull-up resistor (150 kΩ to 450 kΩ) referenced to VCCA.
6 SDAB bidirectional I2C serial data B-side with 1.1 mA integrated current source; no external pull-up resistor permitted.
7 SCLB bidirectional I2C serial clock B-side with 1.1 mA integrated current source; no external pull-up resistor permitted.
8 VCCB power_in B-side supply voltage with operating range 1.65 V to 3.6 V.
