SN74AUC1G17DCKR

Texas Instruments · Flip Flops · SC-70-5

SN74AUC1G17DCKR 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 No internal connection. Leave floating or tie to GND/VCC - pin is not bonded internally.
2 A input Schmitt-trigger logic input. Positive-going threshold VT+ ≈ 0.79 V and negative-going VT- ≈ 0.39 V at VCC = 1.65 V (hysteresis ≈ 0.37 V typ). Input current Ii ≤ ±5 µA over 0 to 2.7 V. Buffered to output Y (Y = A).
3 GND power_in Ground reference (0 V) for the device.
4 Y output Buffered logic output (Y = A). Drives ±8 mA at VCC = 1.65 V (±9 mA at 2.3 V); supports partial-power-down back-drive protection via Ioff.
5 VCC power_in Positive supply. Recommended 0.8 V to 2.7 V (absolute max 3.6 V); optimized for 1.65-1.95 V operation. ICC ≤ 10 µA static.
