Overview
The TS5A4595DCKR is a single-channel SPST analog switch manufactured by Texas Instruments, housed in a five-pin SC-70 package. 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. Power consumption is characterized by a maximum supply current of 500 nA. The component functions within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Single-pole single-throw (SPST) configuration for signal routing
- Low on-resistance suitable for precision applications
- Compatible with 3.3-V and 5-V power domains
Applications
- Portable audio equipment signal path switching
- Battery-powered measurement instruments
- Consumer electronics input selection
Procurement Notes
Verify the specific suffix DCKR against the manufacturer datasheet to confirm the SC-70-5 package type and tape-and-reel quantity. Ensure the order specification matches the required operating temperature range and RoHS compliance status before finalizing procurement documentation.
Selection Notes
Select this component when a low-cost, single-channel switch is required for signals up to 5.5 V. The 8-Ohm on-resistance distinguishes it from lower-resistance alternatives like the TS5A4624. Verify that the 17-ns switching speed meets system timing requirements and that the SC-70-5 footprint fits the board layout constraints.
Part Context
This part belongs to the TS5A4595 series of analog switches. It shares electrical characteristics with the TS5A4595DBVR but utilizes a different surface-mount package. The series is designed for general-purpose signal switching in portable devices requiring low power consumption and small form factors.
Replacement Considerations
The TS5A4595DBVR offers identical electrical specifications but uses a SOT-23-5 package instead of SC-70-5. Other series members may share pinouts but differ in resistance or channel count.
