CD74HCT4067M

The CD74HCT4067M is a high-speed CMOS analog multiplexer/demultiplexer integrated circuit (IC) produced by Texas Instruments. It is part of the 74HCT family, which is known for its high-speed performance and compatibility with TTL (Transistor-Transistor Logic) levels.

Key Features:

1. Functionality: The CD74HCT4067M can route one of 16 input signals to a single output line, or it can route a single input signal to one of 16 output lines, depending on the configuration. This makes it ideal for applications requiring signal selection or routing.

2. Pin Configuration: The IC typically comes in a 24-pin Dual In-line Package (DIP) or a surface-mount package, with pins designated for power supply, ground, control signals, and input/output channels. The pin layout is designed for easy integration into various circuit designs.

3. Voltage Range: The device operates over a wide voltage range, typically from 2V to 6V, making it suitable for both low-voltage and standard logic applications.

4. Control Logic: The CD74HCT4067M uses four control pins (S0 to S3) to select which of the 16 inputs is connected to the output. The control logic is straightforward, allowing for easy interfacing with microcontrollers and other digital logic devices.

5. Low On-Resistance: The IC features low on-resistance (typically in the range of a few ohms), which minimizes signal distortion and power loss when the multiplexer is active.

6. High-Speed Operation: With a propagation delay in the nanosecond range, the CD74HCT4067M is suitable for high-speed applications, including data acquisition systems, communication devices, and audio/video signal routing.

7. Temperature Range: The device is designed to operate over a standard temperature range, making it suitable for various environmental conditions.

8. Applications: Common applications include data routing in communication systems, audio signal switching, sensor multiplexing, and any application requiring the selection of multiple signals.
