Overview
The TMUX6112RTER is a quad single-pole single-throw (SPST) analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. The device features a maximum on-resistance of 160 Ohms with a channel-to-channel matching of 2.5 Ohms. Key electrical parameters include an on-time of 78 ns, off-time of 68 ns, and a -3 dB bandwidth of 800 MHz. It exhibits low leakage current of 20 pA and charge injection of 0.6 pC. The component is housed in a 16-WQFN package with dimensions of 3x3 mm and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Precision switching capability with low on-resistance variation between channels
- High-speed signal routing with sub-100 ns transition times
- Low capacitance design for minimal signal distortion at high frequencies
- Ultra-low leakage current suitable for sensitive measurement applications
Applications
- Data acquisition systems requiring precise signal routing
- Medical instrumentation with strict leakage current requirements
- Industrial process control signal conditioning
- Test and measurement equipment multiplexing
Procurement Notes
Verify the specific ordering suffix RTER corresponds to the reel packaging configuration required for your assembly line. Confirm that the 16-WQFN footprint matches your PCB layout constraints. Ensure compatibility with the specified voltage ranges before integration into the final circuit design.
Selection Notes
Select this component when low leakage and precision are prioritized over ultra-low on-resistance. Compare against TMUX6111 if lower on-resistance is acceptable, or TMUX6113 if higher voltage tolerance is needed. Verify that the 800 MHz bandwidth meets the signal frequency requirements of the application.
Part Context
This part belongs to the TMUX611x family of precision analog switches. It shares the same pinout and general specifications as the TMUX6111 and TMUX6113, differing primarily in on-resistance characteristics and voltage ratings within the series. The RTER suffix indicates tape and reel packaging for automated placement.
Replacement Considerations
Direct functional substitutes within the same family include TMUX6111RTER and TMUX6113RTER. Verify on-resistance differences: TMUX6111 offers lower Ron (160 Ohms typical vs 405 Ohms max for others), while TMUX6113 may have different voltage tolerances. Ensure package compatibility remains 16-WQFN.
