Overview
The SN74LVC2G66DCURG4 is a dual bilateral analog switch manufactured by Texas Instruments, belonging to the SN74LVC2G series. It operates within a supply voltage range of 1.65 V to 5.5 V and supports surface-mount installation in an 8-VSSOP package. The device features two independent SPST-NO circuits with a maximum on-resistance of 10 ohms and channel-to-channel matching of 2 ohms. Key electrical parameters include a -3dB bandwidth of 300 MHz, off-state leakage current of 100 nA, and crosstalk of -58 dB at 1 MHz. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Provides dual independent single-pole single-throw normally-open signal paths for precise analog routing
- Maintains low on-resistance with tight channel-to-channel matching for consistent signal integrity
- Supports high-frequency operation with 300 MHz bandwidth and minimal crosstalk
Applications
- Signal routing in portable consumer electronics
- Battery-powered systems requiring low power consumption
- Audio and video signal switching applications
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance and green manufacturing options as per Texas Instruments standards. Confirm the 8-VSSOP package dimensions match the design footprint. Ensure the -40°C to +85°C industrial temperature rating aligns with the target environment requirements before finalizing procurement.
Selection Notes
Select this component when dual analog switching is required within the 1.65 V to 5.5 V supply range. The 10 ohm on-resistance suits applications demanding low insertion loss. Consider the 8-VSSOP package for space-constrained designs. Verify that the 300 MHz bandwidth meets the signal frequency requirements of the specific application circuit.
Part Context
This part belongs to the SN74LVC2G family of dual analog switches from Texas Instruments. It shares functional similarities with the SN74LVC2G66DCUR but includes the G4 suffix denoting specific environmental compliance attributes. The device complements other LVC logic components for mixed-signal system integration.
Replacement Considerations
The SN74LVC2G66DCUR is listed as a manufacturer-recommended alternative. Other potential substitutes include the NL7WB66USG from onsemi and the 74LVC2G66DC,125 from Nexperia USA Inc., subject to availability and pin compatibility verification.
