Overview
The MC74VHC4051MEL is an analog multiplexer/demultiplexer manufactured by onsemi, belonging to the VHC (Very High Speed CMOS) logic family. It features a single 8:1 channel configuration housed in a 16-lead SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports dual supplies up to ±6 V. Key electrical parameters include a maximum on-resistance of 100 Ohms, a -3dB bandwidth of 80 MHz, and a propagation delay of approximately 35 ns. The component is rated for operation between -55°C and +125°C.
Feature Summary
- High-speed signal switching with low on-resistance for minimal signal attenuation
- Wide analog voltage handling capability across the full power supply range
- Low off-state leakage current to maintain signal integrity when disconnected
Applications
- Data acquisition systems requiring multi-channel signal selection
- Audio routing and switching applications
- Test and measurement equipment signal paths
Procurement Notes
Verify the exact suffix against official documentation, as 'MEL' may denote specific tape-and-reel or packaging variations distinct from standard tube packaging. Confirm end-of-life status through authorized distributors, as this part number appears discontinued in public catalogs. Request RoHS compliance certificates and ensure the source provides traceability for critical electronic components.
Selection Notes
Select this component when high-speed analog switching is required within a 2 V to 6 V logic environment. Compare against HC series counterparts if lower speed but wider voltage tolerance is acceptable. Ensure the 100 Ohm on-resistance meets the application's signal loss requirements. Verify that the 80 MHz bandwidth is sufficient for the highest frequency signals in the design.
Part Context
This device is part of onsemi's VHC logic portfolio, designed to replace older HC series parts where higher speed and lower power consumption are necessary. It serves as a direct functional equivalent to other industry-standard 8:1 analog multiplexers but offers improved switching speeds due to the VHC process technology. It fits into designs previously utilizing metal-gate CMOS switches.
Replacement Considerations
Public records indicate the SN74LV4051ANSR from Texas Instruments as a direct substitute. Verify pin compatibility and electrical parameter alignment before substitution. Other VHC family members like the MC74VHC4052 may serve similar roles if channel count differs.
