Overview
The SN74HC4066DRG4 is a quadruple bilateral analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features four independent SPST channels in a 14-pin SOIC package. The device exhibits a maximum on-resistance of 25 Ω at 5 V, with propagation delays typically around 8 ns. It supports low-level output currents of 5.2 mA and high-level output currents of -5.2 mA. The component functions reliably across an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Provides four independent single-pole single-throw (SPST) analog signal paths for bidirectional switching.
- Maintains consistent on-resistance characteristics compatible with standard CMOS and TTL logic families.
- Supports wide supply voltage operation suitable for diverse digital interface requirements.
Applications
- Signal routing in data acquisition systems
- Multiplexing audio or video signals
- Isolating circuit branches in test equipment
Procurement Notes
Verify the specific suffix DRG4 against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration and RoHS compliance status. Ensure the ordering part number matches the required SOIC-14 package variant before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring multiple analog switches within a single integrated circuit. Consider the 25 Ω on-resistance specification for signal integrity analysis. Verify that the 2 V to 6 V supply range aligns with the system power rails and that the SOIC-14 footprint fits the PCB layout constraints.
Part Context
This part belongs to the SN74HC4066 family of quadruple bilateral analog switches. It shares functional compatibility with other members of the HC series while offering surface-mount packaging options. The device serves as a direct replacement for legacy discrete switching solutions in compact electronic designs.
Replacement Considerations
Cross-reference with SN74HC4066D for identical functionality in different packaging. Verify pinout compatibility with SN74LV4066APWR if lower voltage operation is required, noting potential differences in drive strength and on-resistance specifications.
