Overview
The SN74LVC1G66DCKJ is a single bilateral analog switch from Texas Instruments, housed in a SC-70-5 NanoFree package. It operates on a supply voltage range of 1.65V to 5.5V and supports input voltages up to 5.5V independently of the supply. Key electrical parameters include a maximum propagation delay of 0.8ns at 3.3V, a 3dB bandwidth of 300 MHz, and an on-state resistance typically around 5.5 Ohms. The device features low power consumption with a maximum supply current of 100 nA and handles a switch DC current of 100 mA.
Feature Summary
- Supports high linearity signal switching with a high output voltage ratio
- Enables level translation between different voltage domains due to independent input voltage tolerance
- Provides robust latch-up protection exceeding 100 mA per JESD 78 standards
Applications
- Audio and video signal routing in portable consumer electronics
- Data acquisition systems requiring precise signal path selection
- Battery-powered devices needing efficient power management through signal gating
Procurement Notes
Verify the specific suffix DCKJ corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match your design intent.
Selection Notes
Select this component when a single-channel bilateral switch is required for signals up to 5.5V. The SC-70-5 package offers a compact footprint suitable for space-constrained designs. Consider the 300 MHz bandwidth for applications involving higher frequency analog signals. The low on-resistance ensures minimal signal attenuation across the switch path.
Part Context
This part belongs to the SN74LVC1G66 family of single bilateral analog switches. It is designed for low-voltage digital and analog applications where signal integrity is critical. The LVC technology allows for compatibility with various logic families while maintaining low power consumption. The NanoFree package provides a small outline solution for modern surface-mount assembly techniques.
Replacement Considerations
Direct substitutes within the same family include the SN74LVC1G66DBVR and SN74LVC1G66DCKR. These parts share identical electrical characteristics but may differ in packaging or reel quantity. Verify pin compatibility and thermal performance before substitution.
