Overview
The Nexperia 74HC2G66DC-Q100H is a dual single-pole single-throw analog switch qualified to AEC-Q100 Grade 1. It operates on a single supply voltage ranging from 2.0 V to 10.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device features two independent switches with low ON resistance, typically 30 Ω at 6.0 V. Propagation delay is 11 ns maximum at 6.0 V, while enable time reaches 26 ns maximum. Input leakage current is limited to ±0.2 μA at 9.0 V. The component utilizes a VSSOP8 (SOT765-1) package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 Grade 1 standards
- Wide supply voltage capability supporting operation up to 10.0 V
- High noise immunity with latch-up performance exceeding 100 mA per JESD 78 Class II Level B
Applications
- Automotive signal routing and switching applications
- Battery management systems requiring high-voltage isolation
- Industrial control interfaces for bidirectional data transmission
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that 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 designing circuits requiring dual analog switching within a wide voltage range up to 10.0 V. The HC logic family ensures compatibility with standard CMOS levels. Verify that the thermal dissipation requirements fit within the specified derating curves for the VSSOP8 package. Confirm that the input voltage ratings align with the system's maximum signal amplitudes to prevent clamping diode activation.
Part Context
This device belongs to the Nexperia 74HC2G66-Q100 series, which includes variants such as the 74HC2G66DP-Q100 in a TSSOP8 package. The series shares identical electrical characteristics but differs in physical footprint dimensions. The DC suffix specifically denotes the VSSOP8 plastic very thin shrink small outline package configuration used for space-constrained PCB layouts.
Replacement Considerations
The 74HC2G66DP-Q100 serves as a functional equivalent offering identical electrical performance in a TSSOP8 package. Designers must verify pin-to-pin compatibility and ensure the alternative package fits the existing board footprint constraints.
