Applications

• Stereo Audio Switching: Switch between four different stereo audio sources into one amplifier input without mechanical noise.
• Differential Sensor Arrays: Route pairs of signals from bridge sensors (like Load Cells or Thermocouples) to a single differential ADC.
• Logic Level Conversion: Use the VEE pin to switch analog signals that swing below ground (e.g., -5V to +5V) using standard 0-5V digital logic.

Features

•  Wide range of digital and analog signal levels: digital 3 – 15V, analog to 15Vp-p
• Low “ON” resistance: 80Ω (typ.) over entire 15Vp-p signal-input range for VDD − VEE = 15V
• High “OFF” resistance: channel leakage of ±10 pA (typ.) at VDD − VEE = 10V
• Logic level conversion for digital addressing signals of 3 – 15V (VDD − VSS = 3 – 15V) to switch analog signals to 15 Vp-p (VDD − VEE = 15V)
• Matched switch characteristics: ∆RON = 5Ω (typ.) for VDD − VEE = 15V
• Very low quiescent power dissipation under all digital-control input and supply conditions: 1 µ W (typ.) at VDD − VSS = VDD − VEE = 10V
• Binary address decoding on chip 

Package Includes:

• 1 x CD4052 Differential 4-channel Multiplexer/Demultiplexer IC DIP-16 Package

Frequently Asked Questions (Technical FAQ)

• What is the difference between CD4051 and CD4052?
  The CD4051 is a single 8-channel switch, while the CD4052 is a dual (differential) 4-channel switch.
• Can I switch AC signals with this IC?
  Yes, as long as the peak-to-peak voltage stays within the VDD to VEE range.
• Can I use this with 3.3V logic?
  Yes, the CD4052 can be controlled by 3.3V logic levels when VDD is at 5V.
• Does it matter which side is input or output?
  No, the switches are completely bidirectional.
• What is the "Inhibit" pin for?
  When Inhibit is HIGH, all switches are opened (OFF), regardless of the A and B pin states.
• How do I select Channel 2?
  Set Address A to HIGH and Address B to LOW (Binary 01).
• Can I switch signals higher than VDD?
  No, signals must stay between the supply rails (VEE and VDD) to prevent damage.
• What is "ON Resistance"?
  It is the internal resistance of the switch when closed (~80Ω). This can cause a small voltage drop in high-precision circuits.
• Is this IC suitable for switching power?
  No, it is for signal routing only. It cannot handle high currents (max 25mA).
• Does it support I2C switching?
  It can work for low-speed I2C, but the internal resistance may interfere with pull-up resistors. Dedicated I2C muxes are better for high speeds.
• Can it handle negative voltages?
  Yes, if you provide a negative voltage to the VEE pin.
• What is the crosstalk between X and Y channels?
  Crosstalk is extremely low, but for high-frequency audio, shielding is still recommended.
• Will it work with an ESP32?
  Yes, it is widely used with ESP32 and ESP8266 for analog input expansion.
• Is this a "Break-before-make" switch?
  Yes, it is designed to disconnect the previous channel before connecting the next to prevent shorts.
• What is the maximum frequency it can switch?
  It has a bandwidth of several MHz, making it suitable for video and high-speed audio.
