Overview
The Nexperia 74AHC1G66GW-Q100H is a single-pole, single-throw (SPST) analog switch housed in a 5-TSSOP package. It operates on a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features a maximum ON resistance of 22 Ω at 10 mA load current and 4.5 V to 5.5 V supply. Dynamic performance includes a propagation delay of up to 3.0 ns and enable/disable times reaching 17.0 ns under specified conditions. The component meets AEC-Q100 Grade 1 automotive qualification standards.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 Grade 1 specifications for harsh environments.
- Overvoltage tolerant control input allowing operation in mixed-voltage logic systems.
- High noise immunity and low power dissipation characteristics inherent to CMOS technology.
Applications
- Signal routing in automotive electronic control units
- Level translation between different voltage domains
- Battery management system signal switching
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the procurement channel provides valid traceability records required for automotive-grade components. Cross-reference the manufacturer part number with the most recent product data sheet revision to confirm availability and compliance status before finalizing orders.
Selection Notes
Select this component when a single-channel bidirectional analog switch is required within a 2.0 V to 5.5 V operating range. The 5-TSSOP package is suitable for space-constrained surface-mount designs. Verify that the application's signal levels remain within the absolute maximum ratings to prevent damage. Consider the thermal derating requirements if the total power dissipation exceeds 250 mW at elevated temperatures.
Part Context
This device belongs to the Nexperia 74AHC1G66-Q100 family of automotive qualified analog switches. It shares functional similarities with other SPST switches in the series but is distinguished by its specific TSSOP5 packaging and AEC-Q100 Grade 1 certification. The 'GW' designation indicates the thin shrink small outline package variant.
Replacement Considerations
The 74AHCT1G66GW-Q100 serves as a compatible alternative within the same family, offering similar functionality with TTL-compatible logic thresholds instead of CMOS levels. Both devices share identical pinouts and automotive qualifications, facilitating direct substitution in designs requiring specific input voltage compatibility.
