#148012 - have you looked at 74HC237 with a 1 Hz clock? Responding to: ???'s previous message |
You'd have to use it in combination with an encoder, e.g. '148. Now, if you left out the selector, it might work better with a flipflop array (74HC174) provided you use a switch array that allows only one switch at a time to be activated, as was often used in the telephone industry.
