Hello all. This is my first post here, I require assistance with some analogue-to-digital circuitry. For my school project I am building a digital thermometer. An LM61 is connected to a ADC0808 whichs connects to an EEPROM which outputs BCD to 4511B's which drive 7-segment displays. While reading the **broken link removed** for the ADC0808 I noticed that the output is Tri-State. Does this mean I need resistors branching off from the ADC's output to ground to prevent the EEPROM's address inputs from floating?
Also, would a 555 be suitable for providing the 10-640kHz required for the clock input on the ADC0808?
