Overview
The HEC4066BT-Q100J is a quad single-pole single-throw (SPST) analog switch manufactured by NXP USA Inc. It features four independent bilateral switches, each with two input/output terminals and an active HIGH enable input. The device operates within a supply voltage range of 3 V to 15 V referenced to VSS. It is qualified to the AEC-Q100 standard for automotive applications and supports surface-mount installation in a TSSOP-14 package.
Feature Summary
- Provides four independent bilateral analog switching paths
- Features low on-resistance that remains constant over the full input signal range
- Qualified for automotive electronics under AEC-Q100 standards
Applications
- Analog signal routing in automotive systems
- Digital and analog switching circuits
- Signal multiplexing in industrial control interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 qualification grade for the target application environment. Cross-reference the part number with official distributor catalogs to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a quad SPST analog switch with constant on-resistance is required. Compare its 3 V to 15 V operating range against system power rails. Verify that the TSSOP-14 package dimensions fit the PCB layout constraints. Confirm thermal dissipation requirements are met given the maximum on-resistance values specified in the electrical characteristics table.
Part Context
This part belongs to the HEC4066B family of quad bilateral analog switches. It serves as a robust alternative to older logic families, offering improved on-resistance consistency. The Q100 designation indicates automotive-grade reliability, distinguishing it from standard commercial variants while maintaining pin compatibility with related HEF series devices.
Replacement Considerations
The HEF4066BT is a pin-compatible predecessor. Verify if the updated HEC series parameters meet specific impedance requirements. Other manufacturers offer similar quad analog switches; ensure interface compatibility and voltage ratings align before substitution.
