概述

Description

The 74LVC4066BQ,115 is TI’s quad bilateral switch (four analog transmission gates) in the LVC family. It provides four independent switches that connect Xn to Yn when the corresponding Sn control input is high, and isolate them when low. They can pass signals in either direction, making the device useful for analog multiplexing, signal routing, level shifting, and bus switching in mixed-signal designs.
Key points:
- Four bilateral switches: X1–Y1 with S1, X2–Y2 with S2, X3–Y3 with S3, X4–Y4 with S4
- On state: low, bidirectional on-resistance (RON) varies with Vcc (typical ~tens to ~100 Ω at 5 V)
- Off state: high impedance; good isolation
- Supply: Vcc ≈ 1.65–5.5 V (LVC family)
- Inputs/outputs tolerate signals from GND to Vcc
- Applications: analog routing, multiplexing, level shifting, signal gating
Notes:
- The “BQ,115” suffix denotes packaging/temperature variants; check the datasheet for exact electrical specs and temperature range.

Package

The 74LVC4066BQ,115 comes in a 14‑pin small‑outline package (SOIC‑14).

Pinout

14 pins. Function: 74LVC4066BQ,115 is a quad bilateral (analog) switch. It contains four independent CMOS switches (A1–B1, A2–B2, A3–B3, A4–B4) that bidirectionally connect each pair of ports when its control input is asserted (enable). Used as an analog multiplexer/demultiplexer or signal router with low on-resistance.

Manufacturer

- Manufacturer: Nexperia
- What kind of company: A global semiconductor company that designs and manufactures discrete devices, standard logic ICs (like 74LVC series), and MOSFETs. It is an independent company headquartered in the Netherlands, formed from a spin-off of Philips/NXP’s semiconductor business.

Application

74LVC4066BQ is a quad bilateral switch that passes analog signals under digital control. Each switch can be opened/closed to route signals in either direction.
Common applications:
- Analog signal routing and multiplexing in mixed-signal systems
- Audio/video path switching
- Sensor/instrumentation front-ends (to ADC/DAC)
- Test, measurement, and calibration equipment
- Replacing mechanical relays in low-power portable devices
- Level shifting and impedance matching on buses
- Gating/protection of MCU/FPGA I/O in mixed-signal interfaces

Equivalent

74LVC4066BQ,115 is a quad bilateral switch. Common equivalents from other vendors include:
- CD4066B (Philips/NXP)
- MC14066B (Motorola/ON Semi)
- 74HC4066 (Nexperia)
- 74HCT4066 (TTL-compatible)
- SN74LVC4066 (TI) and other LVC variants
Note: electrical specs (voltage range, Ron, leakage) vary by family; verify datasheets for your application.
