Overview
The MC74VHC4051DT is a single-circuit analog multiplexer/demultiplexer manufactured by onsemi, belonging to the 74VHC series. It features an 8:1 switching configuration housed in a 16-TSSOP surface-mount package. The device operates with a single supply voltage of 2V to 6V or dual supplies of ±2V to ±6V. Key electrical parameters include a maximum on-resistance of 100 ohms, a channel-to-channel matching of 10 ohms, and a -3dB bandwidth of 80MHz. It exhibits a maximum off-state leakage current of 100nA and a channel capacitance of 130pF. The component supports a wide operating temperature range from -55°C to 125°C.
Feature Summary
- Provides bidirectional analog signal routing through eight digitally controlled channels.
- Features low on-resistance for minimal signal attenuation across the passband.
- Includes built-in level shifting to accommodate analog signals exceeding digital control logic levels.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Audio signal routing and mixing applications.
- Test and measurement equipment input multiplexing.
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure the ordering part number matches the required quantity format and moisture sensitivity level requirements for your assembly process. Cross-reference the datasheet revision date to confirm parameter validity before finalizing procurement.
Selection Notes
Select this component when an 8-channel analog switch with VHC speed and 100-ohm on-resistance is required. Compare the 80MHz bandwidth against higher-speed alternatives if signal integrity at frequencies above 50MHz is critical. Verify that the 16-TSSOP footprint aligns with the PCB layout constraints and thermal management capabilities of the target design.
Part Context
This part belongs to the MC74VHC4051 family of CMOS analog multiplexers. It shares functional compatibility with other 74VHC series devices but differs in pin count and channel configuration compared to variants like the MC74VHC4052 (4:1) or MC74VHC4053 (2:1). The DT suffix typically denotes the TSSOP package variant within the product line.
Replacement Considerations
Direct substitutes include the MC74VHC4051MELG, though it utilizes a different SOEIAJ package. Other compatible options may include equivalent 8-channel muxes from Texas Instruments such as the SN74LV4051 series, provided pinout and electrical characteristics are verified against the original design requirements.
