TMUX1101DCKR

Overview

The TMUX1101DCKR is a single-channel analog switch IC from Texas Instruments, configured as a 1 x SPST device. It operates on a single supply voltage ranging from 1.08 V to 5.5 V. The component features a maximum on-state resistance of 4.9 Ohms and a maximum supply current of 1 uA. It is housed in an SC70-5 surface-mount package and supports operation across a temperature range of -40 C to +125 C.

Feature Summary

Ultra-low on-state leakage current specification
Low on-state resistance for signal integrity
Wide single-supply voltage operational range

Applications

Portable instrumentation signal routing
Battery-powered measurement devices
Consumer electronics input selection

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal performance and pinout configuration for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring minimal quiescent current consumption and low leakage in battery-operated systems. Compare the 4.9 Ohm on-resistance against load requirements to ensure acceptable voltage drop. Confirm that the SC70-5 footprint aligns with available board space constraints.

Part Context

This part belongs to the TMUX1101 series of ultra-low power analog switches. It shares core electrical characteristics with other variants in the family but differs in packaging and reel configuration. The DCKR suffix specifically denotes the SC70-5 surface-mount package format intended for high-density assembly applications.
