Overview
The TMUX7612PWR is a four-channel precision analog switch IC from Texas Instruments, housed in a TSSOP-16 package. It features four independent single-pole single-throw (SPST) channels with a maximum on-resistance of 1.4 Ohms and a typical on-resistance of 1.1 Ohms. The device supports a wide supply voltage range of 4.5 V to 50 V for single supplies or ±4.5 V to ±25 V for dual supplies. Key electrical parameters include a maximum operating speed of 2.5 µs turn-on time and 2.2 µs turn-off time, with a maximum supply current of 480 µA. It operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Supports bidirectional analog and digital signals across the full supply voltage range.
- Features ultra-low charge injection to minimize control-to-output coupling and noise.
- Provides break-before-make switching action to prevent signal shorting during channel transitions.
Applications
- Semiconductor test equipment
- Solid-state relays (SSR)
- Programmable logic controllers (PLC)
- Data acquisition systems (DAQ)
Procurement Notes
Verify the specific suffix 'PWR' confirms the TSSOP-16 package and tape-and-reel shipping format. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required pin configuration and thermal characteristics for the target PCB layout.
Selection Notes
Select this component when high voltage tolerance up to 50 V is required alongside low on-resistance. The four-channel SPST configuration suits multiplexing applications. Verify that the 480 µA supply current fits the system power budget. Check if the TSSOP-16 package dimensions are compatible with the assembly constraints.
Part Context
This device belongs to the TMUX7612 family of precision CMOS switches. It shares core specifications with variants like TMUX7612RUMR but differs in packaging. The PWR suffix specifically denotes the TSSOP-16 surface-mount package, distinguishing it from other form factors within the same functional series.
Replacement Considerations
Check for TMUX7612RUMR if a WQFN-16 package is acceptable. Consider TMUX7234PWR for lower power consumption at the cost of higher on-resistance. Verify pinout compatibility before substituting with other TI analog switches.
