Design Interfaces

Digital Signal			Emitter transistor is protected against shorting power supply voltage through no impedance, normally required, thanks to polyswitch. Emitter transistor is protected against shorting power supply voltage through no impedance, normally required, thanks to polyswitch.
"BST82 Driven Rad-Tol" Digital Signal			Principle is to drive the BST82 in the range [-4.5; 4.5] V, which doesn't lead to too high degradation of the gate threshold under radiations while ON (+4.5V). At 1 kGy, expected Vthreshold is around -1 V, perfectly handled by the -4.5 V gate level applied.
Analog Signal \| Single-End			Emitter AOP is protected against over voltage thanks to diodes. Resistor helps to limit stress (output current) on AOP if wrongly connected to any potential. Receiver AOP is protected against over voltage thanks to diodes & with series resistor protecting from over current condition input line (up to 24V typically).
Analog Signal \| Differential			Emitter AOP sends its output voltage through two different wire/lines. Receiver AOP collects the incoming voltage through a protected differential input stage (voltage & current protected).

Pure Volt. Ref >2.5 V		Make sure to count the output system consummed current in the available current from the power source, by a correct choice of R3 resistor. If used with comparator settings variable ref output voltage, check all possible configuration. a TL1431 is given to required a minimum cathode current (worst case) of 1 mA.
Simple Volt. Ref <2.5 V		Care: output current delivered to system will change the reference value. Only work with high impedance input systems. Datasheet indicate 2 mA in the zener (whatever type is) will give steady and precise enough voltage level.
Unused Comparator		From Texas Instruments application note (stored in EDMS: 2742282).
Unused AOP		From Texas Instruments application note (stored in EDMS: 2742282).
