Overview
The SN74LVC1G66QDCKRQ1 is a single-channel SPST analog switch from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and supports signal voltages up to the supply rail. The device features a maximum on-resistance of 25 Ohms and offers low power consumption with a maximum supply current of 100 nA. It provides high-speed switching with a maximum turn-on time of 7.2 ns and a turn-off time of 6.9 ns. The component is housed in a compact SC70-5 package and functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards for durability in vehicle environments.
- Capable of passing full voltage swing signals from ground to the positive supply rail.
- Low static power consumption suitable for battery-powered systems.
Applications
- Signal routing in automotive infotainment and display systems
- Battery management system monitoring circuits
- Portable equipment signal path switching
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and automotive qualification status. Confirm RoHS compliance details through official manufacturer documentation before procurement. Check for specific handling requirements related to moisture sensitivity levels during storage and assembly processes.
Selection Notes
Select this component when a single analog switch with automotive certification is required. Ensure the 25 Ohm on-resistance meets the application's signal integrity needs. Verify that the SC70-5 package dimensions fit the available PCB space and that the operating temperature range aligns with the environmental conditions.
Part Context
This device belongs to the SN74LVC1G66-Q1 family of single analog switches. It shares the LVC logic voltage compatibility and SC70-5 footprint with other members of the series, such as the SN74LVC1G66DRLR, though it differs in automotive qualification and thermal performance specifications.
Replacement Considerations
The SN74LVC1G66DRLR serves as a non-automotive alternative within the same family. Designers must verify if the reduced temperature range and lack of AEC-Q100 certification are acceptable for the target application environment.
