CD74HC4051QPWRQ1

The CD74HC4051QPWRQ1 is a high-speed CMOS analog multiplexer/demultiplexer designed for use in a variety of applications, including signal routing, data acquisition, and analog signal processing. This device is part of the Texas Instruments CD74HC family, which is known for its high-speed performance and low power consumption.

Key Features:

1. Functionality: The CD74HC4051 is an 8-channel analog multiplexer/demultiplexer. It allows one of the eight input signals to be routed to a single output, or vice versa, depending on the configuration. This makes it ideal for applications where multiple signals need to be managed efficiently.

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

3. High-Speed Operation: The CD74HC4051 is designed for high-speed switching, with a propagation delay of around 5 ns at a supply voltage of 5V. This allows for fast signal processing, which is crucial in applications requiring quick response times.

4. Low On-Resistance: The device features low on-resistance (typically around 100 ohms), which minimizes signal distortion and ensures that the signal integrity is maintained when switching between channels.

5. Control Logic: The multiplexer is controlled by three binary select inputs (A, B, and C), which determine which of the eight channels is connected to the output. This allows for straightforward digital control of the analog signals.

6. Package Type: The CD74HC4051QPWRQ1 is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The "Q" in the part number indicates that it is a qualified automotive part, ensuring reliability in automotive environments.

7. Temperature Range: This device is rated for operation over an extended temperature range, typically from -40°C to +125°C, making it suitable for automotive and industrial applications where temperature extremes may be encountered.

8. Applications: Common applications for the CD74HC4051 include audio signal routing, sensor multiplexing, data acquisition systems, and any application requiring the selection of multiple analog signals.

Electrical Characteristics:

• Supply Voltage (Vcc): 2V to 6V
• Input Voltage (Vin): Can handle input voltages up to Vcc
• Output Current: Typically can source or sink up to 25 mA
• Power Consumption: Low static power consumption, making it energy-efficient.
