Hello, Thank u for ur reply. Input to the inverter ic is square pulses, I got inverted square pulses at output of ic. But when next time I powered ON my instrument I didn't get inverted square pulses at output of IC. When I replaced inveter ic I got output. So I concluded that my ic got damaged

Without knowing your devices, circuit and voltages it is impossible to comment.
