Overview
The MC74HCT4066ADR2H is a quad bilateral switch manufactured by onsemi, belonging to the HCT logic family. It integrates four independent single-pole single-throw (SPST) analog switches within a single package. The device operates with a supply voltage range of 2V to 6V and features CMOS inputs compatible with TTL outputs. Key electrical parameters include a maximum on-resistance of 120Ω at 5V, an off-state leakage current of 100nA, and a bandwidth of 160MHz. It supports surface-mount installation in a 14-pin SOIC package and functions across an industrial temperature range from -55°C to +125°C.
Feature Summary
- Integrates four independent bilateral analog switches for signal routing applications
- CMOS input structure ensures compatibility with standard TTL logic levels
- Low on-resistance characteristic facilitates efficient signal transmission
- High isolation capability minimizes crosstalk between channels
Applications
- Data acquisition systems requiring signal multiplexing
- Audio and video signal switching circuits
- Programmable gain amplifier front ends
- Battery management system monitoring paths
Procurement Notes
Verify the specific suffix 'R2H' against official manufacturer documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Cross-reference the full part number with authorized distributors to validate current production status and availability constraints.
Selection Notes
Select this component when designing circuits requiring multiple analog switches controlled by digital logic signals. The HCT series is suitable for systems operating at 5V logic levels. Consider the 120Ω on-resistance variation and 160MHz bandwidth when evaluating signal integrity requirements for high-frequency applications compared to HC series alternatives.
Part Context
This component is part of onsemi's extensive portfolio of 74-series logic devices. The MC74HCT4066A variant serves as a direct replacement for legacy 4066 designs while offering improved speed and lower power consumption. It belongs to the broader category of analog switches and multiplexers used for signal path management in mixed-signal environments.
Replacement Considerations
The MC74HC4066ADR2G is a documented alternative within the same product line. Verify pinout compatibility and electrical parameter alignment before substitution. Other manufacturers offer equivalent parts such as the CD4066BE or SN74HC4066N, though logic family differences may require voltage level adjustments.
