Overview
The TMUX7236PWR is a dual-channel, 2:1 (SPDT) precision analog switch manufactured by Texas Instruments in a 16-pin TSSOP package. It operates on single supplies from 4.5 V to 44 V, dual supplies from ±4.5 V to ±22 V, or asymmetric configurations. The device features latch-up immunity and supports bidirectional signals ranging from VSS to VDD. Key electrical parameters include a maximum on-resistance of 5.4 Ω at 12 V supply, 3.8 Ω at 44 V supply, and 4 Ω at ±15 V supply. Supply current typically ranges from 44 µA to 79 µA depending on voltage conditions.
Feature Summary
- Latch-up immune design prevents high-current events caused by overvoltage.
- Integrated pull-down resistors on logic pins ensure defined states.
- Fail-safe logic allows control pin voltages to be applied before power rails.
- Compatible with 1.8 V logic levels for TTL and CMOS interface.
Applications
- Gas meters
- Flow transmitters
- Factory automation and industrial controls
- Programmable logic controllers (PLC)
- Analog input modules
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-16 package when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required thermal and mechanical specifications for the target PCB layout.
Selection Notes
Select this component for applications requiring high-voltage signal routing up to 44 V. The TSSOP-16 package offers a larger footprint than WQFN variants, which may simplify manual assembly or rework. Verify that the continuous current requirements align with the thermal dissipation limits of the TSSOP package under expected ambient temperatures.
Part Context
This device belongs to the TMUX72xx family of precision switches designed for harsh environments. The PWR suffix specifically denotes the 16-pin Thin Shrink Small Outline Package (TSSOP). This packaging option provides distinct thermal characteristics compared to the WQFN variant, influencing power dissipation capabilities and board layout strategies.
Replacement Considerations
TMUX7236RUMR shares identical electrical specifications but utilizes a WQFN-16 package instead of TSSOP-16. Designers must evaluate thermal performance differences and adjust PCB copper area accordingly when substituting between these package types.
