SN74LVC1G66DB

lingxingic SN74LVC1G66DB LX · Analog Switches, Multiplexers · SOT-23-5

SN74LVC1G66DB from lingxingic SN74LVC1G66DB LX, 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 Y bidirectional Independent input or output terminal of the analog bilateral switch (channel Y side). Bidirectional analog path; conducts to/from Z when E=HIGH. Signal range 0 V to VCC.
2 Z bidirectional Independent output or input terminal of the analog bilateral switch (channel Z side). Bidirectional analog path; conducts to/from Y when E=HIGH. Signal range 0 V to VCC.
3 GND power_in Ground reference (0 V) for the device.
4 E input Active-HIGH enable input. E=HIGH closes the Y-Z switch (ON-state); E=LOW opens the switch (OFF-state, high impedance). Logic input referenced to VCC/GND.
5 VCC power_in Supply voltage input, 1.65 V to 5.5 V recommended (absolute max +6.5 V). Powers the enable buffer and biases the analog switch.
