Overview
The SN74LVC2G66YZAR is a dual single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single power supply ranging from 1.65 V to 5.5 V. The device features a maximum on-resistance of 10 ohms and supports a DC switch current of 100 mA. Electrical performance includes a maximum turn-on time of 3.9 ns and a maximum turn-off time of 6.3 ns. The component provides a -3 dB bandwidth of 300 MHz with an off-state leakage current of 100 nA maximum. It is housed in an 8-DSBGA package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low on-resistance for minimal signal attenuation
- High-speed switching capability for data integrity
- Wide single-supply voltage compatibility
Applications
- Portable equipment signal path management
- Battery-powered system circuit protection
- Audio and video signal switching
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure the ordering information matches the required environmental ratings and RoHS compliance status before finalizing procurement. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics.
Selection Notes
Select this component when a dual-channel analog switch is required within the LVC logic family constraints. Confirm that the 10-ohm on-resistance meets the application's signal loss requirements. Verify that the 8-DSBGA package dimensions fit the available PCB real estate. Ensure the operating voltage range aligns with the system's power supply rails.
Part Context
This part belongs to the SN74LVC2G66 series, which contains two independent SPST switches. It shares functional similarities with other devices in the SN74LVC1G66 family but offers dual channels instead of a single channel. The YZA suffix indicates the specific 8-DSBGA packaging format used for surface-mount assembly.
Replacement Considerations
The SN74LVC2G66YZPR is a confirmed equivalent part number offering identical electrical and mechanical specifications. Verify that any alternative sources match the exact DSBGA footprint and pin configuration.
