RS1T45XH6

Jiangsu RUNIC Tech · Translators, Level Shifters · SOT-23-6

RS1T45XH6 from Jiangsu RUNIC Tech, in a SOT-23-6. 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 Port supply voltage; operate within 1.65V ≤ VCCA ≤ 5.5V.
2 GND power_in Ground reference for the device.
3 A bidirectional Input/output A, referenced to VCCA.
4 B bidirectional Input/output B, referenced to VCCB.
5 DIR input Direction control referenced to VCCA: low enables B-to-A transfer (A port Hi-Z), high enables A-to-B transfer (B port Hi-Z).
6 VCCB power_in B Port supply voltage; operate within 1.65V ≤ VCCB ≤ 5.5V.
