CD4067BM 16CH Analog Multiplexer Demultiplexer IC SOP24

Description

CD4067BM 16CH Analog Multiplexer Demultiplexer IC SOP24

General Description

The CD4067BM is a CMOS 16-channel analog multiplexer/demultiplexer.
It allows one of sixteen analog or digital input/output lines to be connected to a common output/input line.
The channel selection is controlled by 4 binary address lines, and an enable pin allows easy control of the connection state.
It is ideal for analog signal routing, sensor selection, or data acquisition systems.

⚙️ Key Features

• 16-channel single-ended analog multiplexer/demultiplexer

• Wide analog voltage range: 0 V to VDD

• Digital address control: 4-bit binary selection (A, B, C, D)

• Enable input (active LOW) for easy ON/OFF control

• Low ON resistance: typically 125 Ω at 10 V supply

• Low power consumption: CMOS technology

• Bidirectional signal transmission (input or output)

• Break-before-make switching

• Low crosstalk and low leakage current

• Compatible with TTL and CMOS logic levels

⚡ Electrical Characteristics

📦 Pin Configuration (SOP-24)

💡 How It Works

• The 4-bit binary address inputs (D, C, B, A) select one of the 16 channels (Y0–Y15).

• The selected channel is connected to the COM pin when EN = LOW.

• When EN = HIGH, all channels are disconnected (high impedance).

🔧 Applications

• Sensor or signal selection (e.g., 16 analog sensors → 1 ADC input)

• Data acquisition systems

• Audio signal routing

• Measurement instrumentation

• Analog and digital multiplexing/demultiplexing

• Microcontroller expansion for multiple analog sources

🧱 Package Information

• Package Type: SOP-24 (Surface Mount)

• Number of Pins: 24

• Body Width: ~7.5 mm

⚠️ Important Notes

• Ensure the analog signal voltage does not exceed VDD or go below VSS.

• For best linearity, operate with VDD ≥ 10 V when handling analog signals.

• Logic control pins can be driven by 3.3 V or 5 V logic (depending on VDD).
