Overview
The TMUX7412FRRPR is a quad single-pole single-throw (SPST) analog switch from Texas Instruments, housed in a 16-pin WQFN package. It operates with a single supply voltage range of 8 V to 44 V or dual supplies of ±5 V to ±22 V. The device features integrated fault protection capable of blocking overvoltage conditions up to ±60 V relative to ground and ±85 V relative to the power supplies. It includes an active-low interrupt flag for fault status indication and supports 1.8-V logic inputs. Key electrical parameters include a maximum on-resistance of 9.5 Ω, a maximum turn-on time of 740 ns, and a maximum turn-off time of 100 ns.
Feature Summary
- Integrated fault protection blocks overvoltage up to ±60 V during powered and powered-off states.
- Active-low interrupt flag indicates when source inputs exceed supply thresholds.
- Supports 1.8-V logic control independent of the main power supply voltage.
- Latch-up immunity ensures robust operation under extreme electrical stress.
Applications
- Factory automation and control systems
- Programmable logic controllers (PLC)
- Semiconductor test equipment
- Data acquisition systems (DAQ)
Procurement Notes
Verify the specific ordering suffix 'RRP' corresponds to the WQFN-16 package configuration required for your design. Confirm that the component meets RoHS standards if environmental compliance is mandatory for your assembly process. Ensure the selected variant matches the logic control requirements specified in the datasheet.
Selection Notes
Select this component when high-voltage fault tolerance is critical for signal integrity. The device is suitable for applications requiring precise signal routing where power sequencing cannot be strictly controlled. Consider the thermal dissipation capabilities of the WQFN package if operating near maximum temperature limits.
Part Context
This part belongs to the TMUX741xF family, which includes variants with different logic control polarities. The TMUX7412F specifically utilizes logic high signals to enable channels. It shares the same physical footprint and pinout as the TMUX7411F and TMUX7413F, facilitating board layout flexibility within the same product line.
Replacement Considerations
The TMUX7411F and TMUX7413F are direct pin-compatible alternatives within the same series. Selection depends on whether logic low or combined logic levels are preferred for channel activation. Other TMUX series devices may require schematic modifications due to differing voltage ratings or package types.
