TCA9800DGKR

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

TCA9800DGKR 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 within range 0.8 V to 3.6 V
2 SCLA bidirectional Serial clock bus, A-side; connect to VCCA through a pull-up resistor, even if unused
3 SDAA bidirectional Serial data bus, A-side; connect to VCCA through a pull-up resistor, even if unused
4 GND power_in Ground reference
5 EN input Active-high repeater enable input, referenced to VCCA
6 SDAB bidirectional Serial data bus, B-side; do NOT connect to VCCB through a pull-up resistor for proper operation
7 SCLB bidirectional Serial clock bus, B-side; do NOT connect to VCCB through a pull-up resistor for proper operation
8 VCCB power_in B-side and device supply voltage within range 1.65 V to 3.6 V
