When high (logic 1), connects A1 to B1 or C1 depending on the configuration. 5 G2 Control gate for switch 2. When high (logic 1), connects A2 to B2 or C2 depending on the configuration. 6 A2 Input signal to switch 2, control signal that determines whether the switch connects between pins 7 and 8. 7 B2 Output signal from switch 2, connects to A2 through internal circuitry when switch is enabled. 8 C2 Output signal from switch 2, connects to A2 through internal circuitry when switch is enabled. 9 G3 Control gate for switch 3. When high (logic 1), connects A3 to B3 or C3 depending on the configuration. 10 A3 Input signal to switch 3, control signal that determines whether the switch connects between pins 11 and 12. 11 B3 Output signal from switch 3, connects to A3 through internal circuitry when switch is enabled. 12 C3 Output signal from switch 3, connects to A3 through internal circuitry when switch is enabled. 13 G4 Control gate for switch 4. When high (logic 1), connects A4 to B4 or C4 depending on the configuration. 14 A4 Input signal to switch 4, control signal that determines whether the switch connects between pins 15 and 16. 3. Circuit PrincipleThe MC14066BDR2G contains four bilateral switches, each of which can connect two signal paths. Each switch has two inputs (A1, A2, A3, A4) and two outputs (B1, B2, B3, B4 and C1, C2, C3, C4). The switches are controlled by the control signals (G1, G2, G3, G4). When the control signal is high (logic 1), the corresponding switch connects the input to the output. When the control signal is low (logic 0), the switch is open, preventing signal transmission.
4. Pin Function FAQHere are 20 frequently asked questions regarding the MC14066BDR2G:
Q: What is the function of the G1 pin on the MC14066BDR2G? A: G1 is the control gate for switch 1, determining whether the signal path between A1 and B1 or C1 is closed or open.

Q: What happens when the G1 pin is set to low? A: When G1 is set to low, switch 1 is turned off, and no signal path exists between A1, B1, or C1.
Q: Can the MC14066BDR2G be used for high-speed digital switching? A: Yes, the MC14066BDR2G is designed for switching digital signals and can handle high-speed signal paths.
Q: What is the role of pin A1 on the MC14066BDR2G? A: A1 is the input signal for switch 1, which determines the connection to the outputs (B1 and C1) when the switch is enabled.
Q: What happens when pin A1 is connected to ground? A: If A1 is connected to ground, the signal transmitted through switch 1 will either be low or allow for zero voltage transmission, depending on the state of G1.
Q: How many switches does the MC14066BDR2G contain? A: The MC14066BDR2G contains four bilateral switches.
Q: What is the maximum voltage that can be applied to the MC14066BDR2G? A: The MC14066BDR2G can handle a maximum voltage of 15V.
Q: How do I control the switches on the MC14066BDR2G? A: You control the switches through the gate pins (G1, G2, G3, G4) by applying high or low logic signals.
Q: What does a high logic signal on G1 do? A: A high logic signal on G1 enables switch 1 and connects the input at A1 to the output at B1 or C1.
Q: Can the MC14066BDR2G be used in analog signal applications? A: Yes, the MC14066BDR2G is also suitable for analog signal switching in addition to digital signals.
