Overview
The MC74VHC4066DR2 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 within a supply voltage range of 2 V to 12 V and supports an analog input voltage range of 2 V to 12 V. Key electrical parameters include a maximum ON resistance of 120 Ohms, a bandwidth of 160 MHz, and propagation delays of 80 ns for both turn-on and turn-off times. The component is housed in a TSSOP-14 package and functions as a multiplexer/demultiplexer with low OFF-channel leakage current.
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 alternatives.
- Features diode protection on all inputs and outputs to enhance device reliability.
- Offers high ON/OFF output voltage ratio and low crosstalk between switches.
Applications
- Analog signal routing and switching in electronic circuits.
- Multiplexing and demultiplexing applications requiring wide voltage ranges.
- Digital-to-analog and analog-to-digital interface isolation.
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS standards and check for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement plans.
Selection Notes
Select this component when a wide supply voltage range up to 12 V is required, unlike standard 5 V logic families. Consider the 120 Ohm maximum ON resistance and 160 MHz bandwidth for signal integrity requirements. Verify that the TSSOP-14 package fits the PCB layout constraints and thermal management needs of the design.
Part Context
This part belongs to the MC74VHC4066 series of quad analog switches. It serves as a modern replacement for older metal-gate CMOS devices like the MC14066, offering superior linearity and speed. The DR2 suffix typically indicates a specific tape and reel packaging configuration for surface-mount assembly.
Replacement Considerations
The MC74VHC4066D is a compatible variant within the same family. Check datasheets for exact pinout compatibility and ensure electrical parameters such as ON resistance and leakage current meet the application requirements before substitution.
