Overview
The MC74VHC4066MELG is a quad analog switch manufactured by onsemi, utilizing silicon-gate CMOS technology. It features four independent bilateral switches capable of controlling analog and digital voltages across the full power-supply range from VCC to GND. The device operates with a supply voltage between 2.0 V and 12.0 V. Key electrical parameters include a maximum ON resistance of 120 Ohms, a bandwidth of 160 MHz, and propagation delays of 40 ns. It supports single-supply operation and offers low OFF-channel leakage current and improved linearity over input voltage compared to metal-gate CMOS counterparts.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low ON resistances.
- Provides four independent bilateral switches compatible with analog and digital signals across the full supply range.
- Features diode protection on all inputs and outputs to enhance reliability.
Applications
- Signal routing in multiplexer and demultiplexer configurations
- Analog signal switching in instrumentation systems
- Data acquisition systems requiring low crosstalk
Procurement Notes
Verify the specific ordering suffix MELG against the manufacturer's current datasheet to confirm package type and compliance status. Ensure the component meets RoHS requirements if applicable to the target assembly process. Cross-reference the part number with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a quad analog switch with wide voltage compatibility (2V to 12V) is required. It serves as a pin-compatible replacement for older metal-gate CMOS devices like the MC14066 while offering superior linearity and lower ON resistance. Consider the TSSOP-14 package constraints for PCB layout and thermal management during design integration.
Part Context
This part belongs to the MC74VHC4066 series of high-performance silicon-gate CMOS analog switches. It is functionally identical in pinout to the HC4066A and MC14066 but provides enhanced performance characteristics such as faster propagation delays and lower noise. The series is designed for applications requiring reliable signal switching across a wide dynamic voltage range.
Replacement Considerations
The MC74VHC4066DTR2G is a verified substitute within the same family, differing primarily in packaging configuration. Other pin-compatible alternatives include parts from the 74VHC4066 family, though electrical parameters should be compared against the original datasheet specifications.
