Overview
The TMUX1219DCKR is a single-channel, general-purpose analog switch manufactured by Texas Instruments. It features a 1 x SPDT configuration housed in an SC70-6 surface-mount package. The device operates on a single supply voltage ranging from 1.08 V to 5.5 V and supports bidirectional analog and digital signals from GND to VDD. Key electrical specifications include a maximum on-resistance of 6 Ohms and a maximum power supply current of 1.5 µA. It functions reliably within an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports bidirectional signal transmission for both analog and digital applications across the full supply voltage range.
- Features ultra-low quiescent current consumption suitable for portable and battery-powered designs.
- Provides high reliability with extended industrial temperature rating capabilities.
Applications
- Portable consumer electronics
- Building automation systems
- General-purpose signal switching
Procurement Notes
Verify the specific suffix DCKR against official datasheets to confirm the SC70-6 package type and reel packaging format. Ensure compatibility with the required 1.08V to 5.5V supply rails and check that the 6 Ohm on-resistance meets circuit impedance requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when a single-pole double-throw switch is required for low-voltage applications. The wide input voltage range allows flexibility in system design without level shifting. Consider the SC70-6 footprint for space-constrained PCB layouts. Verify that the 1.5 µA standby current aligns with strict power budget constraints in battery-operated devices.
Part Context
This part belongs to the TMUX1219 series of CMOS analog switches. It shares core functional characteristics with other variants like the TMUX1219DBVR, differing primarily in package style (SC70-6 versus SOT-23-6). The series is designed for general-purpose multiplexing tasks requiring low power and small form factors.
Replacement Considerations
The TMUX1219DBVR serves as a direct functional alternative with identical electrical parameters but utilizes an SOT-23-6 package instead of SC70-6. Designers must verify pin-to-pin compatibility and physical footprint differences before substitution.
