SN74LVC2G17QDCKRQ1

Texas Instruments · Buffer/Driver/Transceiver · SC-70-6

SN74LVC2G17QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 1A input Input to buffer 1; Schmitt-trigger input that accepts voltages up to 5.5 V.
2 GND power_in Ground reference; per the datasheet, unused inputs must be held at VCC or GND for proper operation.
3 2A input Input to buffer 2; Schmitt-trigger input that accepts voltages up to 5.5 V.
4 2Y output Output of buffer 2; drives ±24 mA at 3.3 V and is disabled by the Ioff circuitry during partial-power-down to prevent backflow current.
5 VCC power_in Supply voltage, specified for 1.65 V to 5.5 V operation.
6 1Y output Output of buffer 1; drives ±24 mA at 3.3 V and is disabled by the Ioff circuitry during partial-power-down to prevent backflow current.
