4051BDC

Overview

The National Semiconductor 4051BDC is an analog multiplexer/demultiplexer IC. It provides a single 8-channel switch with common output. Key electrical parameters include a maximum on-resistance of 600 ohms and a supply voltage range of 3V to 18V for single supply operation. Switching times are specified at a maximum of 500ns for both turn-on and turn-off. The device features a channel capacitance of 5pF and a maximum leakage current of 100nA. It operates within a temperature range of -40°C to 85°C and is housed in a 16-DIP package.

Feature Summary

  • Provides eight independent signal paths selectable via digital control inputs
  • Supports wide analog signal voltage ranges compatible with various logic families
  • Offers low power consumption suitable for battery-operated applications

Applications

  • Data acquisition systems requiring signal routing
  • Industrial process control for sensor multiplexing
  • Audio switching circuits for channel selection

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, following the acquisition. Confirm the specific suffix 'BDC' corresponds to the required temperature grade and packaging variant. Request official datasheets to validate pinout compatibility and electrical limits against original design specifications before integration.

Selection Notes

Select this component when an 8-channel analog switch with through-hole mounting is required. Ensure the application voltage stays within the 3V to 18V single-supply limit. Consider the 600-ohm on-resistance for signal integrity requirements. Verify that the 16-DIP package fits the PCB layout constraints compared to surface-mount alternatives.

Part Context

This part belongs to the CMOS analog multiplexer family, functionally similar to the CD4051 series. It serves as a standard solution for routing multiple analog signals to a single destination. The device is widely used in general-purpose electronic designs where signal switching is necessary.

Replacement Considerations

Compatible substitutes include the CD4051BDC from other manufacturers. Verify pin compatibility and electrical parameter equivalence. Ensure the replacement supports the same 16-DIP package and operating temperature range.
