SN74AUC2G66DCTR

Texas Instruments · Analog Switches, Multiplexers · MSOP-8

SN74AUC2G66DCTR from Texas Instruments, in a MSOP-8. 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 passive Analog switch 1 A-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V).
2 1B passive Analog switch 1 B-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V).
3 2C input Control input for analog switch 2; logic low sets the switch OFF and logic high sets it ON, with control input voltage rated 0 V to 3.6 V.
4 GND power_in Ground reference; all voltages are specified with respect to ground.
5 2A passive Analog switch 2 A-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V).
6 2B passive Analog switch 2 B-side input/output terminal; the I/O port voltage is limited to 0 V to VCC (absolute maximum -0.5 V to VCC + 0.5 V).
7 1C input Control input for analog switch 1; logic low sets the switch OFF and logic high sets it ON, with control input voltage rated 0 V to 3.6 V.
8 VCC power_in Supply voltage, recommended 0.8 V to 2.7 V (absolute maximum -0.5 V to 3.6 V); unused inputs must be held at VCC or GND.
