Overview
The HEF4066BT-Q100J is a quad single-pole single-throw analog switch qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 3.0 V to 15.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features four independent bidirectional switches with active HIGH enable inputs. Static characteristics include an OFF-state leakage current of up to 7.5 μA at 5 V and input leakage of ±1.0 μA at 15 V. ON resistance varies by voltage, peaking at 2500 Ω at 5 V and 175 Ω at 15 V. Dynamic propagation delays reach a maximum of 140 ns.
Feature Summary
- Automotive qualification in accordance with AEC-Q100 (Grade 1)
- Wide supply voltage range from 3.0 V to 15.0 V
- High noise immunity and fully static operation
- ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
Applications
- Industrial and automotive systems
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the complete part number including suffixes against official Nexperia documentation to ensure correct package type and temperature grade. Confirm that the specific ordering code matches the required SO14 package variant. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring automotive-grade reliability and wide voltage compatibility. Ensure the application logic respects the active HIGH enable requirement for switch activation. Verify that the peak ON resistance values at the target supply voltage meet the signal integrity requirements. Check thermal derating curves if operating near the upper temperature limit.
Part Context
This component belongs to the HEF4066B-Q100 family of quad analog switches manufactured by Nexperia. It utilizes the SO14 plastic small outline package (SOT108-1). The device is designed as a CMOS low-power solution suitable for replacing mechanical relays in switching applications where size and power consumption are critical constraints.
Replacement Considerations
Direct substitutes include other AEC-Q100 qualified quad SPST analog switches from compatible manufacturers. Verify pinout compatibility and ON resistance specifications when considering alternatives. Ensure the replacement device meets the same -40 °C to +125 °C operating temperature range.
