According to what I understand in the datasheet and the given truth table, pulling the DIR pin 0 high 5V and the OE pin 19 low 0V should result in the A side channels to be passed to the B side channels. However, instead of measuring a 5V potential at B2 when 5V is present at A2, no voltage is passed through the other side.

I've tried fiddling around with the direction pin but receive the same results in either direction. It sounds like you may have a short on the output or the chip is damaged. The wiring looks proper.

A x to B x I have a breadboard wired up in this configuration: However, instead of measuring a 5V potential at B2 when 5V is present at A2, no voltage is passed through the other side.

Am I missing something in the datasheet or is it a possibility I have come across a bad chip? Use a 1K series resistor.

Your test will work just as well but your IC might live longer. It would be impossible to 3-state the outputs if it had them. Active Oldest Votes. Rob B. Sign up or log in Sign up using Google.
