Overview
The 74HC4066DB,118 is a quad single-pole single-throw analog switch manufactured by Nexperia. It features four independent switches with two input/output terminals and an active HIGH enable input per channel. The device operates within a supply voltage range of 2.0 V to 10.0 V and supports ambient temperatures from -40 °C to +125 °C. Typical ON resistance values are 50 Ω at 4.5 V, 45 Ω at 6.0 V, and 35 Ω at 9.0 V. Propagation delay ranges from 10 ns to 18 ns depending on voltage. It includes input clamp diodes for overvoltage protection and meets JEDEC ESD standards exceeding 2000 V (HBM).
Feature Summary
- Quad SPST analog switch configuration with bidirectional signal paths.
- Active HIGH enable control logic for individual channel switching.
- Integrated input clamp diodes allowing interface to voltages exceeding VCC.
- ESD protection compliant with JEDEC standards for robust operation.
Applications
- Analog signal routing and gating in electronic circuits.
- Audio and video signal path selection.
- Data acquisition systems requiring multiplexing.
- Battery management and power monitoring interfaces.
Procurement Notes
Verify the ordering suffix '118' against current Nexperia documentation to confirm specific tape-and-reel packaging or variant details. Ensure compatibility with existing PCB footprints for the SO14 package. Confirm availability status as product lifecycles may change. Cross-reference pin assignments with the official datasheet before integration.
Selection Notes
Select this component when a low-cost, quad-channel analog switch is required for general-purpose signal routing. Verify that the maximum ON resistance and leakage currents meet system requirements at the intended operating voltage. Consider thermal dissipation limits if driving significant load currents across multiple channels simultaneously.
Part Context
This part belongs to the 74HC/HCT family of CMOS logic devices, specifically designed as analog switches. It serves as a functional equivalent to other industry-standard quad SPST switches. The 'DB' designation indicates the SO14 plastic small outline package variant.
Replacement Considerations
Compatible substitutes include SN74HC4066 (Texas Instruments) and MC74HC4066 (onsemi). Verify pinout compatibility and electrical parameter alignment before substitution.
