Overview
The Nexperia 74HC2G66DP-Q100H is a dual single-pole single-throw analog switch qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 2.0 V to 10.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features low ON resistance, typically 41 Ω at 4.5 V and 30 Ω at 6.0 V. Static characteristics include an OFF-state leakage current of 1.0 μA maximum at 9.0 V. Dynamic performance specifies a propagation delay of 15 ns maximum at 4.5 V and enable times up to 30 ns. The component is housed in an SOT505-2 TSSOP8 package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 standards
- Wide supply voltage operation ranging from 2.0 V to 10.0 V
- Low ON resistance ensuring efficient signal transmission
- High noise immunity with latch-up performance exceeding 100 mA
Applications
- Automotive electronic systems requiring robust analog switching
- Signal routing in multi-voltage environments
- Battery management system signal paths
- Infotainment system input/output switching
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature grade. Ensure compliance with RoHS and REACH regulations as stated in the chemical content data. Confirm that the intended application does not exceed the absolute maximum ratings defined in the datasheet limiting values section.
Selection Notes
Select this component when dual SPST analog switching is required in space-constrained automotive designs. The wide supply voltage range allows compatibility with various system power rails. Verify that the ON resistance characteristics meet the signal integrity requirements for the specific load conditions and voltage levels present in the target circuit design.
Part Context
This part belongs to the 74HC2G66-Q100 family of dual analog switches manufactured by Nexperia. It shares functional similarities with other members of the series but is distinguished by its specific automotive qualification and TSSOP8 packaging. The product line emphasizes low power consumption and high reliability for demanding operational environments.
Replacement Considerations
The 74HCT2G66DP-Q100 serves as a compatible alternative within the same family, offering similar functionality with HCT logic level inputs. Both devices utilize the SOT505-2 package and share identical pin configurations. Designers should verify input voltage thresholds and ON resistance specifications to ensure compatibility with existing circuit parameters.
