Supply original CD74HC4051PWRG4, Interface - Analog Switches, Multiplexers, Demultiplexers, by Texas Instruments

The CD74HC4051PWRG4 is a high-speed CMOS analog multiplexer/demultiplexer designed for use in a variety of applications, including signal routing, data acquisition, and analog switching. It is part of the Texas Instruments 74HC family, which is known for its high-speed performance and low power consumption.

Key Features:

1. Functionality: The CD74HC4051PWRG4 can route one of eight analog inputs to a single output or vice versa. It operates as an 8-channel multiplexer/demultiplexer, allowing for flexible signal management in electronic circuits.

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: With a propagation delay of around 5 ns at 5V, the CD74HC4051PWRG4 is capable of handling fast signal switching, which is essential in high-speed data applications.

4. Low On-Resistance: The device features a 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 select lines (S0, S1, S2), which determine which of the eight inputs is connected to the output. The control logic is compatible with standard CMOS and TTL logic levels.

6. Package Type: The CD74HC4051PWRG4 is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The "G4" suffix indicates that the part is lead-free and compliant with RoHS standards.

7. Temperature Range: The device is rated for operation over a temperature range of -40°C to +125°C, making it suitable for industrial and automotive applications.

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