4 Additional Features

1.8-V Control Logic – Switches with this feature have a built-in voltage translator to prevent voltage mismatch between the supply rail and the control logic. VIH and VIL levels are compatible with the 1.8-V logic levels at any voltage supply. See the Simplifying Design With 1.8 V logic MUXes and Switches Tech Note for more information.
Fail-Safe Logic – Ensures the switch stays off and the voltage on the logic pin (VSEL) does not back-power VDD when VSEL is greater than VDD. See the Switches and muxes: What is fail-safe logic? training video from TI Precision Labs.
GUID-B7CDDD7C-9685-4AAF-9503-2F37E423DD46-low.gifFigure 4-1 Fail-Safe Logic
Injection Current Control — Devices with Injection Current Control shunt injected current on disabled (high-Z) signal pathways to ground. This mitigates error on the active signal pathway as the injected current is going into the ground rail and not the power rail. See the Switches and muxes: Prevent crosstalk with injection current control training video from TI Precision Labs.
GUID-B867420F-7823-4CB4-BE21-151C8F262656-low.gifFigure 4-2 Injection Current Control
Integrated Pulldown Resistor on Logic Pin – Internal weak pulldown resistors to GND to ensure the logic pins are not floating.
GUID-B21B91A1-4276-45AC-A225-A91E36D3D962-low.gifFigure 4-3 Integrated Pulldown Resistor on Logic Pin
Latch-Up Immunity – Devices that are latch-up immune can use various methods to achieve latch up immunity such as being built in a Silicon On Insulator (SOI) process, employing the use of guard rings, or a mix between different methods. When these measures are taken Electrical Overstress, Electrically Fast Transients, and Injected Currents will not cause latch up in these devices. See the Switches and muxes: What is latch-up immunity? training video from TI Precision Labs.

Overvoltage Protection – When the input voltage VI/O exceeds the defined threshold voltage, VTH or VT, the switch enters the high impedance state, isolates signal path, and protects downstream components. Depending on device the threshold can determined in 1 of 3 ways.
  • Fixed Threshold
  • Threshold = Supply
  • Threshold = Configurable
Figure 4-5 Overvoltage Protection
Undervoltage Protection – When the input voltage VI/O falls below the defined threshold voltage, VTH, the switch enters the high impedance state, isolates signal path, and protects downstream components. Depending on device the threshold can determined in 1 of 2 ways.
  • Threshold = Supply
  • Threshold = Configurable
This feature typically exists alongside Overvoltage Protection
Figure 4-6 Undervoltage Protection
Fault Flag Indicators – On some devices there is a fault flag pin that will change states (typically from high to low) when a fault is present on the device and will return to its default state when the fault is cleared.
Figure 4-7 Fault Flag Indicators

Drain Response Output – On some protection switches/multiplexers the output response of a device during a fault condition can be set to either clamp to supply or open circuit the output.

Figure 4-8 Drain Response Output
Powered-Off Protection – Protects switch and isolates signal path when signals are present at the I/O pins and VDD = 0 V. See the Switches and muxes: Simplify power sequencing with powered-off protection training video from TI Precision Labsand the Eliminate Power Sequencing With Powered-off Protection Signal Switches Tech Note for more information.
