Overview
The TS5A4594DCKR is a single-channel SPST analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2 V to 5.5 V. The device features a maximum on-resistance of 8 Ohms and supports a DC switch current of 100 mA. Electrical performance includes a maximum turn-on time of 17 ns and a maximum turn-off time of 14 ns. Quiescent current is limited to 500 nA maximum. The component functions within an operating temperature range of -40°C to +85°C and is housed in a SC70-5 surface-mount package.
Feature Summary
- Single-pole single-throw (SPST) configuration for signal routing
- Low on-resistance characteristic for minimal signal loss
- Ultra-low quiescent current consumption for power efficiency
- High-speed switching capability with nanosecond transition times
Applications
- Portable consumer electronics requiring low-power signal switching
- Battery-powered instrumentation systems
- Audio and video signal path selection circuits
Procurement Notes
Verify the specific ordering suffix DCKR to confirm the SC70-5 package type and reel packaging configuration. Ensure compatibility with standard surface-mount assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated product lines.
Selection Notes
Select this component when a single channel with 8 Ohm on-resistance is required within a 2V to 5.5V supply range. Compare against TS5A3166 if lower on-resistance is needed, or TS5A4624 if SPDT configuration is necessary. Verify that the SC70-5 footprint meets board space constraints.
Part Context
This part belongs to the TS5A4594 series of general-purpose analog switches. It shares electrical specifications with variants such as TS5A4594DBVR, which utilizes a SOT-23-5 package. The series is designed for applications demanding small form factors and low power operation in portable devices.
Replacement Considerations
TS5A4594DBVR offers identical electrical performance in a SOT-23-5 package. TS5A3166DCKR provides lower on-resistance in the same SC70-5 package but differs in speed characteristics.
