Overview
The SN74AUC2G66DCUR is a dual bilateral analog switch manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It operates on a single supply voltage ranging from 0.8 V to 2.7 V. The device features two independent SPST switches with a maximum on-resistance of 15 Ohms and a maximum power supply current of 10 µA. Each switch supports a DC switch current of 100 mA. Signal integrity is maintained with a maximum operating time of 2.3 ns and an off-time of 2 ns. The component functions reliably within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Dual bilateral analog switching capability for signal routing
- Low power consumption suitable for battery-operated systems
- High-speed signal transmission with minimal propagation delay
Applications
- Portable consumer electronics requiring low-voltage operation
- Battery-powered instrumentation and measurement devices
- Signal multiplexing in communication equipment
Procurement Notes
Verify the specific ordering suffix against official Texas Instruments documentation to confirm the package type and tape-and-reel specifications. Ensure that the procurement channel provides valid traceability for the SN74AUC2G66 series. Cross-reference the manufacturer part number with authorized distributor databases to confirm current production status and compliance with relevant environmental standards before finalizing acquisition.
Selection Notes
Select this component when designing circuits that require low-voltage analog switching between 0.8 V and 2.7 V. The SN74AUC2G66DCUR is appropriate for applications demanding low on-resistance and high bandwidth in compact surface-mount layouts. Compare its electrical characteristics against alternative logic families to ensure compatibility with existing system voltage levels and signal integrity requirements.
Part Context
This device belongs to the SN74AUC2G series of ultra-low-voltage analog switches. It shares functional similarities with other members of the family but differs in packaging and specific suffix designations. The SN74AUC2G66 variant specifically provides dual bilateral switches, distinguishing it from multiplexer or demultiplexer configurations within the same product line.
Replacement Considerations
The SN74LVC2G66DCUR serves as a recommended alternative from the same manufacturer. Verify voltage compatibility, as the LVC variant typically supports higher supply voltages than the AUC series.
