Overview
The TS3A5018DR is a quad single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.65V to 3.6V, featuring a maximum on-resistance of 10 ohms and a low power consumption of 7 uA. The device provides high bandwidth with a -3dB frequency of 300 MHz and fast switching times of 8 ns for turn-on and 6.5 ns for turn-off. Packaged in a 16-SOIC surface-mount format, it supports a continuous DC current of 100 mA per channel and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Quad SPDT configuration enabling four independent signal paths
- Low on-resistance of 10 ohms for minimal signal attenuation
- High bandwidth performance suitable for RF applications
- Ultra-low quiescent current for battery-powered systems
Applications
- Audio and video signal routing
- Portable consumer electronics
- Mobile phone accessory detection
- MP3 players and digital cameras
Procurement Notes
Verify the specific package variant against design requirements, as the TS3A5018 series includes multiple form factors such as TSSOP, UQFN, and SOIC. Confirm that the DR suffix corresponds to the SOIC-16 reel packaging intended for automated assembly processes. Ensure compatibility with standard surface mount reflow profiles during procurement planning.
Selection Notes
Select this component when a compact solution for multi-channel signal switching is required under low voltage constraints. The 10-ohm on-resistance ensures signal integrity for audio and video lines. Consider the 16-SOIC package for ease of prototyping or if board space allows for wider pitch compared to QFN alternatives. Validate thermal dissipation capabilities given the 100 mA continuous current rating.
Part Context
This part belongs to the TS3A5018 family of analog switches designed for portable devices. It shares functional similarities with other members like the TS3A5018PW and TS3A5018RSVR but differs in physical packaging. The DR designation specifically identifies the tape-and-reel version of the 16-pin SOIC package, distinguishing it from tube-packed or smaller footprint variants within the same product line.
Replacement Considerations
Direct pin-compatible substitutes include TS3A5018PW and TS3A5018RSVR. Verify package dimensions and lead configurations before substitution to ensure mechanical fit. Electrical parameters remain consistent across these variants.
