Overview
The TS5A1066DCKRG4 is a single-channel, normally-open SPST analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65V to 5.5V and features a maximum on-resistance of 10 ohms. The device supports a -3dB bandwidth of 400MHz with charge injection of 1pC and off-state channel capacitance of 6.8pF. Maximum leakage current is 200nA, and power consumption is limited to 1uA. Switching times are specified at 5.5ns for turn-on and 4.5ns for turn-off. It functions within an ambient temperature range of -40°C to 85°C and is housed in a SC-74A (SOT-753) surface-mount package.
Feature Summary
- Low on-resistance of 10 ohms for minimal signal attenuation
- High-speed switching with 400MHz bandwidth capability
- Ultra-low power consumption suitable for battery-operated systems
- Compact SOT-753 package design for space-constrained applications
Applications
- Portable consumer electronics requiring low-power signal routing
- Battery-powered measurement instruments
- Audio and video signal path switching
- Communication equipment interface protection
Procurement Notes
Verify the G4 suffix indicates lead-free packaging compliant with RoHS standards. Confirm the SC-74A package designation matches the required footprint. Ensure the operating temperature range meets environmental specifications. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a single-channel analog switch with low on-resistance and high bandwidth is required. The 1.65V minimum supply voltage makes it suitable for modern low-voltage logic interfaces. Consider the 10-ohm resistance for signal integrity requirements. Verify that the SOT-753 package dimensions fit the PCB layout constraints compared to alternative packages like SOT-23-5.
Part Context
This part belongs to the TS5A1066 family of analog switches from Texas Instruments. The DCKR variant denotes the SC-74A package with reel packaging, while the G4 suffix specifies lead-free construction. It shares core electrical characteristics with other members of the series but differs in physical packaging and compliance markings.
Replacement Considerations
The TS5A1066DBVR offers identical electrical performance in a SOT-23-5 package. The TS5A2066 provides dual channels in an SM8 package. Verify pin compatibility and package dimensions when substituting these alternatives.
