Overview
The MC74HC4066ADG is a quad bilateral analog switch manufactured by onsemi using high-performance silicon-gate CMOS technology. It features four independent SPST switches with low ON resistance and low OFF-channel leakage current. The device supports a wide power-supply voltage range of 2.0 V to 12.0 V, allowing control of analog signals across the full supply range. Key electrical parameters include a maximum ON resistance of 70 Ω at 9.0 V or 12.0 V supply, propagation delays ranging from 10 ns to 40 ns depending on voltage, and an operating temperature range of -55°C to +125°C. It is housed in a SOIC-14 package.
Feature Summary
- Utilizes silicon-gate CMOS technology for fast switching speeds and improved linearity compared to metal-gate CMOS equivalents.
- Provides four independent bilateral switches capable of controlling analog and digital voltages within the full power-supply range.
- Includes diode protection on all inputs and outputs to guard against electrostatic discharge damage.
- Features low crosstalk between switches and low noise characteristics suitable for precision signal routing.
Applications
- Multiplexer and demultiplexer circuits for signal routing
- Sample-and-hold amplifier configurations
- Gate arrays for analog signal processing
- LSTTL/NMOS to HCMOS interface applications
Procurement Notes
Verify the specific ordering suffix 'DG' corresponds to the SOIC-14 package and Pb-Free status as defined in the manufacturer's ordering information. Confirm that the component meets RoHS compliance requirements if applicable to your assembly process. Check for any automotive-specific variants if AEC-Q100 qualification is required for your application environment.
Selection Notes
Select this component when a quad analog switch with wide voltage compatibility (2V to 12V) is needed. Ensure the ON resistance specifications meet your signal integrity requirements at the intended supply voltage. Consider the SOIC-14 package dimensions for PCB layout constraints and verify thermal dissipation capabilities within the recommended operating temperature range.
Part Context
This part belongs to the MC74HC4066A family of quad analog switches. It is pin-compatible with older metal-gate CMOS devices like the MC14016 and MC14066 but offers superior performance characteristics including lower ON resistance and better linearity over the input voltage range due to its silicon-gate construction.
Replacement Considerations
Direct pin-compatible replacements include other manufacturers' 74HC4066 variants such as SN74HC4066 or CD74HC4066. Verify electrical parameters like ON resistance and propagation delay match your design requirements before substitution.
