Overview
The NLVVHC1G66DTT1G is a single-pole single-throw (SPST) normally open analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 3.6 V and features low on-resistance of 8 Ω at 3.3 V. The device supports bidirectional signal flow with a breakdown voltage exceeding 3.6 V. Key electrical parameters include an on-state resistance variation of 20 Ω, input/output leakage current of ±1 µA, and dynamic capacitance of 0.7 pF. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low dynamic capacitance minimizes signal distortion in high-speed data lines
- Low on-resistance ensures minimal signal attenuation during conduction
- Bidirectional switching capability allows flexible signal routing configurations
Applications
- Portable multimedia devices requiring efficient power management
- High-speed data line protection circuits
- Cellular phone peripheral interface switching
Procurement Notes
Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and material declarations as stated in the product datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component for applications requiring low voltage operation below 3.6 V. Consider the 8 Ω on-resistance for signal integrity requirements. Evaluate the 0.7 pF capacitance for high-frequency performance needs. Confirm that the SOT-353 package fits the available PCB real estate constraints.
Part Context
This device belongs to the NLVVHC1G series of ultra-low voltage analog switches. It is designed for portable electronics where power efficiency is critical. The series offers small footprint solutions compared to standard voltage logic switches. It complements other onsemi logic families targeting mobile and battery-powered systems.
Replacement Considerations
Publicly confirmed substitutes include MC74VHC1G66DTT1G and MC74VHC1GT66DTT1G from onsemi. These parts share similar SPST functionality and pinout compatibility. Verify voltage ranges and package dimensions before substitution.
