Overview
The MC74VHC4066MEL is a quad analog switch manufactured by onsemi, utilizing silicon-gate CMOS technology. It functions as a bilateral switch, multiplexer, or demultiplexer capable of controlling analog and digital voltages across the full power-supply range from VCC to GND. The device features four independent switches with low ON resistance and high OFF-channel leakage current isolation. It operates within a wide supply voltage range of 2.0 V to 12.0 V. Key electrical parameters include a maximum ON resistance of 120 Ohms, propagation delay of 40 ns, and bandwidth of 160 MHz. The component is housed in a TSSOP-14 package and supports an operating temperature range from -55°C to +125°C.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low noise performance.
- Provides improved linearity and lower ON resistance over input voltage compared to metal-gate CMOS equivalents.
- Features diode protection on all inputs and outputs to handle voltage transients.
- Control inputs are compatible with standard CMOS outputs and LSTTL outputs when pullup resistors are used.
Applications
- Analog signal routing in data acquisition systems
- Multiplexing/demultiplexing in communication interfaces
- Sample-and-hold circuits requiring low distortion
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type, tape-and-reel specifications, and compliance status. Ensure the requested part number matches the exact mechanical dimensions and marking requirements for your assembly process. Cross-reference with authorized distributors to confirm current production status and availability.
Selection Notes
Select this component when a quad SPST analog switch is required with a wide 2V to 12V operating range. It is suitable for applications demanding low crosstalk and high ON/OFF output voltage ratios. Consider the TSSOP-14 package for surface-mount designs needing compact footprints. Compare ON resistance linearity and propagation delays against alternative VHC series devices if speed or signal integrity is critical.
Part Context
This part belongs to the MC74VHC4066 family of quad analog switches. It shares pinout compatibility with the older metal-gate CMOS MC14066 and high-speed CMOS HC4066A families. The VHC series offers enhanced performance characteristics, including faster propagation delays and lower ON resistance, while maintaining backward compatibility with existing circuit layouts designed for previous generations.
Replacement Considerations
Publicly confirmed substitute part numbers include MC74VHC4066DR2G and MC74VHC4066DTR2G. These alternatives share identical functional specifications and pinouts. Verify that the replacement variant matches the required packaging format and temperature grade before implementation.
