Overview
The 74HC4066PW/AUJ 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 on a single supply voltage ranging from 2.0 V to 10.0 V. 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 reaches a maximum of 18 ns at 4.5 V. The component is housed in a TSSOP14 package (SOT402-1) and supports operating temperatures from -40 °C to +125 °C.
Feature Summary
- Quad configuration providing four independent bilateral analog switches
- Low ON resistance that remains relatively constant across the full input signal range
- ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model
- Input clamp diodes allowing interface to voltages exceeding VCC using current limiting resistors
Applications
- Signal routing in data acquisition systems
- Audio and video signal switching applications
- Programmable gain amplifier circuits
- Sample-and-hold circuit implementations
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant and temperature rating. Confirm RoHS compliance status directly with the supplier or through the latest product data sheet revision history before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring low ON resistance and high-speed switching within a wide voltage range. Ensure the application voltage does not approach 2.0 V if linear analog transmission is required, as non-linearity increases significantly near this threshold. Verify thermal dissipation requirements based on the TSSOP14 package derating curves.
Part Context
This part belongs to the 74HC/HCT4066 family of quad analog switches. It is pin-compatible with the legacy HEF4066B but offers superior electrical performance. The PW suffix specifically denotes the TSSOP14 plastic thin shrink small outline package, distinguishing it from SO14 or QFN variants within the same logical family.
Replacement Considerations
The 74HCT4066PW serves as a direct functional replacement where TTL-level inputs are preferred over CMOS levels. Other manufacturers producing JEDEC-compliant 74HC4066 devices in TSSOP14 packages may also be suitable substitutes pending verification of pinout and electrical parameters.
