Overview
The MC74HC4051DTEL is a single 8-channel analog multiplexer/demultiplexer manufactured by onsemi, formerly Motorola. It utilizes silicon gate CMOS technology to provide eight bidirectional analog switches controlled by three digital select lines (A, B, C). The device supports a wide supply voltage range of 2V to 6V for both single and dual supplies. Key electrical parameters include a maximum on-resistance of 100 ohms, an off-state leakage current of 200nA, and a bandwidth of 80MHz. It operates within a temperature range of -55°C to 125°C and is housed in a 16-TSSOP package.
Feature Summary
- Provides eight bidirectional analog signal paths selectable via three digital control inputs.
- Features low on-resistance and high off-isolation for effective signal routing.
- Includes built-in level shifting to accommodate analog signals exceeding the digital logic supply voltage.
- Offers extended industrial temperature operation capabilities.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Programmable gain amplifier circuits.
- Audio signal routing and switching matrices.
- Test and measurement equipment input multiplexing.
Procurement Notes
Verify component authenticity through authorized distribution channels due to historical manufacturing transitions from Motorola to onsemi. Confirm RoHS compliance status as legacy variants may differ. Check for obsolescence notices or lifecycle changes affecting long-term availability. Ensure the specific suffix corresponds to the required tape-and-reel packaging configuration for automated assembly processes.
Selection Notes
Select this component when an 8-channel analog switch with low on-resistance and wide supply voltage compatibility is required. Compare against HC, HCT, and VHC logic families based on speed and drive requirements. Verify that the TSSOP package dimensions fit the target PCB footprint. Consider thermal dissipation limits if multiple channels are active simultaneously under heavy load conditions.
Part Context
This part belongs to the standard 74HC4051 family of analog multiplexers. It is functionally equivalent to other manufacturers' 74HC4051 devices but carries the onsemi branding following the semiconductor division's history. The DTEL suffix specifically denotes the 16-lead Thin Shrink Small Outline Package (TSSOP) with tape and reel delivery format.

FAQ
What is the maximum analog input voltage range?
The device supports a supply voltage range of 2V to 6V. With dual supplies, it can handle analog signals up to the respective positive and negative rail voltages.
Does the device support bidirectional signal flow?
Yes, all eight channels are bidirectional, allowing the common pin to act as either input or output depending on the system configuration.
What is the typical on-resistance value?
The maximum on-resistance is specified at 100 ohms, ensuring low insertion loss for analog signals within the operating voltage range.
