#81875 - ...or roll your own AND gate Responding to: ???'s previous message |
Two diodes and one resistor. Connect both anodes to one end of the resistor and the other end of the resistor to +5. Connect RD to one cathode and WR to the other. The anode/resistor junction is the output. Use a resistor of around 2-4 K.
