Overview
The MC74VHC4066DTR2 is a quad bilateral switch manufactured by onsemi, belonging to the 74VHC series. It features four independent SPST switches in a TSSOP-14 package. The device operates with a supply voltage range of 2 V to 12 V and supports an operating temperature range from -55°C to +125°C. 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. Power dissipation is rated at 450 mW.
Feature Summary
- Provides four independent single-pole single-throw (SPST) analog signal paths within a single integrated circuit.
- Supports high-voltage operation up to 12 V, enabling compatibility with diverse signal levels.
- Features low power consumption characteristics typical of advanced CMOS technology.
Applications
- High-speed data acquisition systems requiring signal routing
- Battery-powered equipment due to low standby current
- Portable instruments utilizing wide voltage ranges
Procurement Notes
Verify the specific suffix 'DTR2' against official datasheets to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a quad analog switch is required with a wide supply voltage range extending to 12 V. It is suitable for applications needing moderate switching speeds and low on-resistance. Consider the TSSOP-14 package constraints for PCB layout. Compare performance metrics such as bandwidth and leakage current against alternative logic families if stricter signal integrity is needed.
Part Context
This component is part of the 74VHC family, which combines high-speed CMOS performance with standard TTL-compatible inputs. The MC74VHC4066 variant specifically offers four bilateral switches, distinguishing it from single or dual-channel alternatives. It serves as a solid-state replacement for mechanical relays in signal routing applications.
Replacement Considerations
The MC74VHC4066DR2 is a documented substitute offering identical functionality in a SOIC-14 package. Verify pinout compatibility and thermal characteristics during substitution. Other variants in the 74VHC4066 series may differ in packaging or temperature ratings.
