TCA9802DGKR

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

TCA9802DGKR 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, operating range 0.8 V to 3.6 V.
2 SCLA bidirectional A-side serial clock bus, which must be connected to VCCA through a pull-up resistor even if unused.
3 SDAA bidirectional A-side serial data bus, which must be connected to VCCA through a pull-up resistor even if unused.
4 GND power_in Ground reference for the device.
5 EN input Active-high repeater enable input, referenced to VCCA.
6 SDAB bidirectional B-side serial data bus, which must not be connected to VCCB through a pull-up resistor for proper operation and should be left floating if unused.
7 SCLB bidirectional B-side serial clock bus, which must not be connected to VCCB through a pull-up resistor for proper operation and should be left floating if unused.
8 VCCB power_in B-side and device supply voltage, operating range 1.65 V to 3.6 V.
