概述
Description
74LVC4066BQ is a quad bilateral analog switch (four transmission-gate switches) in the LVC CMOS family. Each channel connects its A and B terminals when the common control input is enabled, and becomes high-impedance when off. It’s used to multiplex or route analog or mixed-signal signals in low-voltage systems.
Key points:
- Four independent switches with a single enable control
- Operation typically from about 1.65 V to 5.5 V
- Bidirectional signal path with on-resistance in the tens of ohms (varies by Vcc)
- Off leakage is low; suitable for analog/digital signal routing within rails
- Package options usually include 14-pin SOP/TSSOP/etc.
The suffix “BQ, 115” relates to package/temperature grade; “115” often denotes extended temperature (verify in the datasheet for the exact rating). Typical apps: portable electronics signal routing, sensor interfaces, ADC/DAC front-ends.

Pinout
- Pin count: 14 pins (DIP14/SO14 variants common for 74LVC4066BQ,115).
- Function: Quad bilateral analog switch (four transmission-gate switches). Each switch connects its two signal pins (Xn and Yn) when the corresponding control input Sn is asserted; otherwise it presents a high-impedance off-state. The four switches are: X1–Y1 (controlled by 1S), X2–Y2 (2S), X3–Y3 (3S), X4–Y4 (4S). Requires VCC and GND pins.
