74LVC1G66LT05ARCQ

GR · Analog Switches, Multiplexers · SOT-23-5

74LVC1G66LT05ARCQ from GR, in a SOT-23-5. 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 A bidirectional Bidirectional analog/digital signal to be switched. Switch I/O voltage range 0 V to VCC; on-resistance typ 2.5 Ω at VCC = 4.5 V. Paired with pin B through the analog switch.
2 B bidirectional Bidirectional analog/digital signal to be switched. Switch I/O voltage range 0 V to VCC; forms the other terminal of the bilateral switch with pin A.
3 GND power_in Ground reference pin (0 V). All voltages are referenced to this pin.
4 C input Digital control input for the switch: L = OFF (switch open), H = ON (switch closed). Accepts input voltages up to 5.5 V; VIH ≈ VCC×0.7 (VCC×0.65 at 1.65-1.95 V), VIL ≈ VCC×0.3 (VCC×0.35 at 1.65-1.95 V).
5 VCC power_in Positive supply voltage input. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Supply current ICC ≤ 10 µA at 5.5 V.
