Overview
The MC74HC4051DTR2 is an analog multiplexer/demultiplexer manufactured by onsemi, originally associated with the Motorola brand lineage. It features a single circuit configuration providing an 8:1 switching capability within a 16-TSSOP surface-mount package. The device operates on a single supply voltage ranging from 2V to 6V or dual supplies of ±2V to ±6V. Key electrical parameters include a maximum on-resistance of 100 ohms and a channel-to-channel matching of 10 ohms. It supports a -3dB bandwidth of 80MHz with an off-state leakage current of 200nA maximum. The component functions reliably across an extended industrial temperature range of -55°C to 125°C.
Feature Summary
- Provides high-speed signal routing with an 80MHz bandwidth for analog applications.
- Ensures signal integrity through low on-resistance and tight channel matching specifications.
- Supports flexible power configurations with wide single and dual supply voltage ranges.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Audio signal routing and processing circuits.
- Industrial control systems utilizing analog sensor inputs.
Procurement Notes
Verify the manufacturer designation carefully, as the part number reflects historical Motorola branding now managed by onsemi. Confirm RoHS compliance status, as older Motorola-branded variants may differ from current onsemi production standards. Ensure the specific suffix matches the required packaging format. Cross-reference datasheets to confirm pinout compatibility if replacing legacy components. Validate that the operating temperature range meets your system requirements.
Selection Notes
Select this component when an 8:1 analog switch is needed with moderate speed and low distortion. Compare the 100-ohm on-resistance against load requirements to ensure acceptable voltage drop. Consider the 16-TSSOP package dimensions for PCB layout constraints. Evaluate the 200nA leakage current against sensitive signal paths. Verify that the 2V to 6V supply range aligns with the system's available power rails.
Part Context
This component belongs to the 74HC4051 family of CMOS analog multiplexers. It serves as a standard interface solution for routing multiple analog signals to a single output path. The device is widely used in mixed-signal environments where digital control interfaces with analog data streams. Its compatibility with standard logic levels simplifies integration into microcontroller-based designs.
