Overview
The Nexperia 74HC2G66DP-Q100/AH is a dual single-pole single-throw analog switch in an SOT505-2 (TSSOP8) package. It operates on a single supply voltage ranging from 2.0 V to 10.0 V. The device features low ON resistance, typically 41 Ω at 4.5 V and 30 Ω at 6.0 V. It supports an ambient temperature range of -40 °C to +125 °C and includes input clamp diodes for overvoltage protection. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
- Wide supply voltage capability supporting operation up to 10.0 V
- Low ON resistance characteristics optimized for signal integrity
- High noise immunity with latch-up performance exceeding 100 mA
Applications
- Automotive electronic systems requiring qualified analog switching components
- Signal routing in multi-voltage environments
- Audio and video signal path selection
Procurement Notes
Verify the specific ordering suffix AH against the manufacturer's current documentation to confirm package variant and marking details. Ensure the procurement source provides valid traceability records for AEC-Q100 compliance. Confirm that the delivered components match the specified TSSOP8 package dimensions and lead configuration.
Selection Notes
Select this component when a dual SPST analog switch is required for automotive or industrial applications operating between 2.0 V and 10.0 V. Consider the 74HCT2G66 variant if the system strictly utilizes 5 V logic levels. Verify that the thermal dissipation requirements fit within the 250 mW total power limit for the TSSOP8 package.
Part Context
This part belongs to the Nexperia 74HC/HCT2G66-Q100 family of dual analog switches. It shares functional similarities with other members like the 74LVC2G66 but differs in supply voltage ranges and drive capabilities. The DP suffix indicates the TSSOP8 package, while the Q100 designation confirms its automotive qualification status.
Replacement Considerations
The 74HCT2G66DP-Q100 serves as a compatible alternative for 5 V logic systems. Other Nexperia dual analog switches may be considered if pin compatibility and package size are maintained. Verify electrical parameters such as ON resistance and leakage current before substituting.
