Overview
The Nexperia 74HC1G66GW-Q100H is a single-pole, single-throw (SPST) analog switch qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates with a supply voltage range of 2.0 V to 10.0 V and features an active HIGH enable input. The device utilizes a TSSOP5 (SOT353-1) package with five leads. Static characteristics include an ON resistance typically ranging from 18 Ω to 128 Ω depending on the supply voltage and current conditions. Dynamic performance includes propagation delays up to 90 ns at 2.0 V and -3 dB bandwidths reaching 180 MHz at 4.5 V.
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 specifications
- Wide operating supply voltage range supporting 2.0 V to 10.0 V operation
- High noise immunity with CMOS low power dissipation characteristics
- Robust ESD protection exceeding 2000 V via Human Body Model
Applications
- Automotive electronic systems requiring qualified analog switching components
- Mixed voltage environments utilizing overvoltage tolerant control inputs
- Signal routing in battery management and infotainment circuits
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature grade. Ensure compliance with RoHS3 directives and REACH regulations prior to integration. Confirm that the selected variant matches the required AEC-Q100 Grade 1 qualification status for the intended automotive application environment.
Selection Notes
Select this component when a single-channel analog switch with wide voltage tolerance is required. The HC logic family supports interfaces up to 10.0 V, distinguishing it from lower-voltage alternatives. Verify that the TSSOP5 footprint aligns with the PCB layout constraints and thermal requirements for the target ambient temperature range.
Part Context
This part belongs to the Nexperia 74HC1G66-Q100 series, which also includes the 74HCT1G66-Q100 variant. The HCT version offers reduced input threshold levels specifically designed for interfacing with TTL logic levels, whereas the HC version provides standard CMOS thresholds. Both share identical pin configurations and automotive qualifications.
Replacement Considerations
The 74HC1G66GV-Q100 serves as a direct functional replacement using the SC-74A (SOT753) package. Designers must verify mechanical fitment differences between the TSSOP5 and SC-74A footprints during substitution.
