4051BDM

Overview

The CD4051BDM is an analog multiplexer/demultiplexer manufactured by National Semiconductor, now part of Texas Instruments. It features a single 8-channel configuration with logic-level conversion capabilities. The device operates within a supply voltage range of 3V to 18V. Key electrical parameters include a maximum on-resistance (Ron) of 240 Ω and an on-resistance matching specification of 5Ω. The component provides a nominal off-state isolation of 40 dB. It supports a wide operating temperature range from -55°C to 125°C and utilizes a 16-pin DIP package.

Feature Summary

Integrates logic-level conversion for direct interface with various digital logic families
Provides low on-resistance for efficient signal transmission
Offers high off-state isolation to minimize channel crosstalk

Applications

Data acquisition systems requiring multi-channel signal selection
Programmable gain amplifier circuits
Digital potentiometer implementations

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature rating. Confirm RoHS compliance status if environmental regulations apply to the final assembly, as older batches may not meet current standards.

Selection Notes

Select this component when an 8-channel analog switch with integrated level shifting is required. Compare the 240 Ω maximum on-resistance against system loss requirements. Verify that the 18V maximum supply voltage aligns with the available power rails in the target design environment.

Part Context

This part belongs to the CD405x series of CMOS analog multiplexers. The 'B' suffix typically denotes the military or extended industrial temperature grade (-55°C to 125°C), distinguishing it from commercial variants. The 'DM' suffix indicates the specific plastic DIP-16 package format used for through-hole mounting.

Replacement Considerations

Direct substitutes include the CD4051BM and CD4051BC. Check datasheets for pin compatibility and ensure the replacement maintains the required 8-channel architecture and logic-level conversion features.
