Overview
The Nexperia 74HC4066PW,112 is a quad single-pole single-throw analog switch housed in a TSSOP14 (SOT402-1) package. It operates on a supply voltage range of 2.0 V to 10.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features four independent switches with active HIGH enable inputs. Typical ON resistance values are 50 Ω at 4.5 V, 45 Ω at 6.0 V, and 35 Ω at 9.0 V. Maximum propagation delay is 18 ns at 4.5 V and 12 ns at 9.0 V. Turn-on time reaches a maximum of 30 ns at 4.5 V, while turn-off time peaks at 45 ns under the same conditions.
Feature Summary
- Provides four independent bilateral analog switches controlled by active HIGH logic inputs.
- Features low ON resistance that varies predictably with supply voltage levels.
- Includes input clamp diodes allowing safe interfacing with voltages exceeding VCC using current limiting resistors.
- Offers robust electrostatic discharge protection compliant with JEDEC standards for both human body model and charged device model.
Applications
- Signal routing in data acquisition systems
- Audio signal switching and multiplexing
- Programmable gain amplifier circuits
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration. Ensure the component matches the required TSSOP14 footprint dimensions and lead pitch specifications for your PCB layout. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement orders.
Selection Notes
Select this component when a CMOS-compatible quad analog switch is required within a 2 V to 10 V operating range. The TSSOP14 package is suitable for surface-mount applications requiring a thin profile. Consider the typical ON resistance characteristics relative to your specific supply voltage to ensure adequate signal transmission performance.
Part Context
This part belongs to the 74HC4066 series of quad SPST analog switches manufactured by Nexperia. It utilizes standard CMOS logic technology and is designed for general-purpose signal switching applications. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package variant.
Replacement Considerations
Direct replacements include the 74HC4066D (SOIC-14 package) and other variants listed in the 74HC_HCT4066 datasheet. Verify pin compatibility and package dimensions before substitution.
FAQ
How does the ON resistance change with supply voltage?
The typical ON resistance decreases as the supply voltage increases, measuring approximately 50 Ω at 4.5 V, 45 Ω at 6.0 V, and 35 Ω at 9.0 V.
What is the function of the enable input?
The enable input (nE) controls the state of the switch. When nE is LOW, the analog switch is turned off. When nE is HIGH, the switch is turned on.
Can the inputs interface with voltages higher than VCC?
Yes, the inputs include clamp diodes which allow the use of current-limiting resistors to interface inputs to voltages in excess of VCC.
