Overview
The TS5A9411DCKTG4 is a single-channel, low-resistance SPDT analog switch manufactured by Texas Instruments. It functions as a 2:1 multiplexer or demultiplexer with an on-resistance of 10 ohms. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports bidirectional signal flow. Key electrical parameters include a leakage current of less than 1 nA at 25°C and an ON/OFF isolation of 35 dB. It features a low charge injection of 0.7 pC and operates across a temperature range of -40°C to +85°C. The component is housed in a compact SC-70 package.
Feature Summary
- Single-channel SPDT configuration for signal routing
- Low on-resistance for minimal signal loss
- Bidirectional switching capability
- Compact surface-mount packaging
Applications
- Portable audio equipment signal path selection
- Cellular phone accessory detection circuits
- MP3 player and mobile phone input/output switching
- Battery-powered consumer electronics
Procurement Notes
Verify the G4 suffix indicates lead-free and RoHS compliance per Texas Instruments standards. Confirm the DCKT package designation matches the required SC-70 physical dimensions for your PCB layout. Ensure the operating environment stays within the specified -40°C to +85°C range for reliable performance.
Selection Notes
Select this component when a single-pole double-throw switch is required in space-constrained designs. It is suitable for applications needing low power consumption and high isolation between channels. Consider the 10-ohm on-resistance for signal integrity requirements in audio or data lines.
Part Context
This part belongs to the TS5A9411 family of analog switches from Texas Instruments. It is designed for portable devices where small footprint and low power are critical. The device integrates protection features to handle signals beyond the supply rails, enhancing system robustness in mobile applications.
Replacement Considerations
Direct substitutes include the TS5A9411DCKR variant, which shares identical electrical characteristics but may differ in reel packaging specifications. Verify pin compatibility and thermal performance before swapping.
