Zero output for AD8010

HI,

we are implementing 2 to 1 multiplexing circuit using AD8180.

Application1: Toggle between 0V and 1.3V using SELECT  Pin ( i.e, 0/5V TTL).

Application2: Toggle between -0.6 V and -5V using SELECT  Pin ( i.e, 0/5V TTL).

In both cases we are getting zero output even with Enable pin Low (GND) and Select pin toggle between 0V and 5V.

By suspecting IC failure i have replaced with new ones.but facing same problem.

please suggest a solution.

Regards

GPR
