Texas Instruments · Analog Switches, Multiplexers · SOIC-14

CD74HCT4066M96 from Texas Instruments, in a SOIC-14. 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 1Y bidirectional Input/output pin for Switch 1, accepts analog signals from 0V to VCC.
2 1Z bidirectional Input/output pin for Switch 1, accepts analog signals from 0V to VCC.
3 2Z bidirectional Input/output pin for Switch 2, accepts analog signals from 0V to VCC.
4 2Y bidirectional Input/output pin for Switch 2, accepts analog signals from 0V to VCC.
5 2E input Control input for Switch 2; high logic level (≥2V) enables the switch, low level (≤0.8V) disables it.
6 3E input Control input for Switch 3; high logic level (≥2V) enables the switch, low level (≤0.8V) disables it.
7 GND power_in Ground pin.
8 3Y bidirectional Input/output pin for Switch 3, accepts analog signals from 0V to VCC.
9 3Z bidirectional Input/output pin for Switch 3, accepts analog signals from 0V to VCC.
10 4Z bidirectional Input/output pin for Switch 4, accepts analog signals from 0V to VCC.
11 4Y bidirectional Input/output pin for Switch 4, accepts analog signals from 0V to VCC.
12 4E input Control input for Switch 4; high logic level (≥2V) enables the switch, low level (≤0.8V) disables it.
13 1E input Control input for Switch 1; high logic level (≥2V) enables the switch, low level (≤0.8V) disables it.
14 VCC power_in Positive supply voltage, 4.5V to 5.5V, over operating temperature range -55°C to 125°C.
