Overview
The TMUX1101DBVR is a single-channel analog switch IC manufactured by Texas Instruments, housed in a compact SOT-23-5 surface-mount package. It operates on a single supply voltage ranging from 1.08 V to 5.5 V and supports signal voltages up to 5.5 V. The device features an ultra-low on-state leakage current of 3 pA and a maximum on-resistance of 4.9 Ohms. Designed for low-power applications, it draws a maximum supply current of 1 uA. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low leakage current specification minimizes signal distortion in high-impedance circuits
- Low on-resistance ensures minimal signal attenuation during conduction
- Single-supply operation simplifies power management in portable systems
- Compact SOT-23-5 footprint optimizes board space utilization
Applications
- Battery-powered portable instrumentation
- Automotive sensor signal conditioning
- Medical equipment signal routing
- Industrial process control systems
Procurement Notes
Verify the complete part number including the suffix DBVR to confirm the specific tape-and-reel packaging configuration. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Confirm that the operating voltage requirements align with the 1.08 V to 5.5 V range specified in the datasheet before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring minimal signal leakage and low on-resistance in space-constrained environments. The wide operating temperature range makes it suitable for harsh industrial or automotive conditions. Consider the single-channel SPST configuration for simple signal path switching applications where power consumption must be minimized.
Part Context
This device belongs to the TMUX1101 series of ultra-low leakage analog switches. The family shares similar electrical characteristics but varies in package options and channel configurations. The DBVR suffix specifically denotes the SOT-23-5 package variant optimized for automated surface-mount assembly processes.
Replacement Considerations
Direct pin-compatible alternatives within the same series include TMUX1101DCKR (SC-70-5 package). Verify package dimensions and thermal characteristics when substituting different package variants to ensure mechanical fit.
