XTR116: Problem while using XTR116

Part Number: XTR116

Tool/software:

I am observing 40ma current when the circuit is powered by 24V DC

This is observed under following conditions: U3= XTR116, Q1= FCX690D

R6=100K, R11 =250Ohms, R5=R11=0 ohm, 

Capacitor end of R8 is grounded, ESD protection norms followed.

3 times IC changed results are same 

I am expecting 4ma current but in reality, it is 40ma.

Please explain how to resolve the situation
