Overview
The MC74VHC4066DR2G is a quad analog switch manufactured by onsemi, utilizing silicon-gate CMOS technology. It operates within a power supply voltage range of 2 V to 12 V and features four independent bilateral switches in a TSSOP-14 package. Key electrical parameters include a maximum on-resistance of 120 Ohms, a bandwidth of 160 MHz, and propagation delays of 40 ns. The device supports single-supply operation with an operating temperature range from -55°C to +125°C and a maximum power dissipation of 450 mW.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and low on-resistance linearity across the full power-supply range.
- Provides four independent bilateral switches capable of controlling analog and digital voltages varying from VCC to GND.
- Includes diode protection on all inputs and outputs to safeguard against electrostatic discharge events.
Applications
- Analog signal routing in data acquisition systems
- Multiplexing and demultiplexing of audio or video signals
- Battery-powered equipment requiring low standby current
Procurement Notes
Verify the specific ordering suffix DR2G to confirm the TSSOP-14 surface-mount package and tape-and-reel packaging format. Ensure compliance with RoHS directives and Pb-free status requirements for the target assembly process. Confirm that the extended industrial temperature rating aligns with the operational environment specifications.
Selection Notes
Select this component when a wide supply voltage range up to 12 V is required compared to standard 3.3 V or 5 V logic families. The VHC series offers improved speed and lower on-resistance linearity over input voltage compared to older metal-gate CMOS alternatives like the MC14066. Verify that the 120 Ohm maximum on-resistance meets the signal integrity requirements of the application.
Part Context
This part belongs to the MC74VHC4066 series of high-performance silicon-gate CMOS analog switches. It serves as a modern replacement for legacy metal-gate devices such as the MC14066 and HC4066A, offering identical pinouts while providing superior switching performance and broader voltage compatibility.
Replacement Considerations
Publicly confirmed substitutes include the MC74VHC4066DTR2G and MC74VHC4066DR2. These variants share the same functional core but may differ in package type or reel configuration.
