Overview
The TMUX4051PWR is a single-channel, 8:1 CMOS analog multiplexer manufactured by Texas Instruments. It operates with a single supply voltage ranging from 5V to 24V or dual supplies up to ±12V. The device supports bidirectional analog signals across the source and drain pins within the supply range. Key electrical specifications include a maximum on-resistance of 60Ω at 25°C, an off-isolation of -95dB at 1MHz, and a bandwidth of 430MHz at 24V. It features 1.8V logic compatibility, break-before-make switching, and ESD protection rated at 2000V HBM. The component is housed in a 16-pin TSSOP package.
Feature Summary
- Supports bidirectional signal paths with rail-to-rail operation across wide supply ranges
- Features 1.8V logic compatible thresholds for TTL and CMOS interface compatibility
- Incorporates break-before-make switching to prevent input shorting during transitions
- Provides high off-isolation and low capacitance for signal integrity preservation
Applications
- Analog multiplexing and demultiplexing systems
- Factory automation and control equipment
- Battery test equipment
- Medical instrumentation
- Building automation and grid infrastructure
Procurement Notes
Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-16 package variant when sourcing. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supplier provides valid traceability documentation. Check for any recent product change notifications regarding marking or packaging updates.
Selection Notes
Select this component when an 8:1 multiplexing configuration is required with high voltage tolerance up to 24V. It is suitable for designs needing 1.8V logic interface compatibility without level shifting. Consider the 60Ω on-resistance and 430MHz bandwidth against system signal requirements. Verify thermal performance within the TSSOP-16 package for the intended ambient temperature range.
Part Context
The TMUX4051PWR belongs to the TMUX405x family of general-purpose CMOS multiplexers. This series includes the TMUX4052 (4:1, 2-channel) and TMUX4053 (2:1, 3-channel switch). All devices in the family share pin compatibility with industry standard 4051, 4052, and 4053 muxes, facilitating direct upgrades or replacements in existing designs.
Replacement Considerations
Pin-compatible alternatives include the industry standard CD74HC4051. Verify voltage ratings and speed parameters as legacy parts may differ significantly from the 24V capability of the TMUX4051.
