I have just implemented an ADG3304 level translator into a new design and it is not functioning as expected. I am hoping others have had experience with this particular IC and can point me into a direction that yeilds the correct results.
I am using the ADG3304 to connect an MCU operating at 3.3V to drive a TTL signal operating at 5.0V. The problem that I am experiencing is that when the A side goes to logic low (0V), the Y side goes to 2.5V instead of zero volts. I have attempted to connect a pull down resister to the Y output to see if this would allow the signal to go to zero volts, however, it does not. When the A side goes to logic high, the output also goes to logic high (5V) as expected. The issue is when it goes to logic low. Since TTL devices have a on threshold of about 1.2V, this 2.5 volts output is creating a huge problem for me.
