Overview
The 74HC4066DB,112 is a quad single-pole single-throw analog switch manufactured by Nexperia. It features four independent switches with two input/output terminals (nY and nZ) and an active HIGH enable input (nE). The device operates within a supply voltage range of 2.0 V to 10.0 V. Key electrical characteristics include a typical ON resistance of 50 Ω at 4.5 V and 35 Ω at 9.0 V. Propagation delay ranges from 10 ns to 18 ns depending on the supply voltage. The component supports an ambient temperature range of -40 °C to +125 °C and is housed in an SO14 plastic small outline package.
Feature Summary
- Quad configuration providing four independent SPST analog switches
- Bidirectional signal transmission capability between input/output terminals
- Integrated clamp diodes for interfacing with voltages exceeding VCC
- ESD protection compliant with JEDEC standards
Applications
- Signal gating and modulation circuits
- Audio and video signal routing
- Digital control of frequency, impedance, and phase
- Motor speed control systems
Procurement Notes
Verify the specific ordering suffix '112' against current Nexperia documentation to confirm availability and exact package variant. Confirm that the SO14 package matches the design requirements. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a low-cost CMOS quad analog switch is required. Ensure the application voltage does not exceed the 10.0 V maximum rating. Consider the ON resistance variation across the operating voltage range. Verify that the SO14 package dimensions fit the PCB layout constraints.
Part Context
This part belongs to the 74HC/HCT logic family, specifically designed as an analog switch. It serves as a functional alternative to other quad SPST switches like the 74HC4053, though it lacks multiplexing capabilities. The device is widely used in general-purpose signal switching applications requiring bidirectional flow.
Replacement Considerations
Publicly confirmed substitutes include the 74HCT4066 variants for TTL-compatible logic levels. Other manufacturers produce equivalent parts such as the SN74HC4066. Verify pin compatibility and electrical specifications before substitution.
