SN74LVC1G07QDCKRQ1

Texas Instruments · Buffer/Driver/Transceiver · SC-70-5

SN74LVC1G07QDCKRQ1 from Texas Instruments, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected Not connected. No internal connection; leave floating or tie to a fixed potential per board practice.
2 A input Buffer input. CMOS logic input, 5.5 V-tolerant regardless of VCC. Drives the open-drain output Y (Y = A per the function table: A=L → Y=L, A=H → Y=Hi-Z).
3 GND power_in Ground reference for the device (0 V).
4 Y output Open-drain buffer output. Sinks up to 32 mA (IOL max at VCC = 4.5 V). Requires an external pull-up to VPU (≤ 5.5 V); can be wired-OR/AND with other open-drain outputs.
5 VCC power_in Supply voltage. Operating range 1.65 V to 5.5 V; data-retention 1.5 V min. Bypass with 0.1 µF close to the pin.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (24 pp, sha256 57d88b2f0db6fd23, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
