How to implement HD74HC32 (quadruple 2-input positive-OR gate)?
I'm struggling to implement the HD74HC32 (quadruple 2-input positive-OR gate) package:
My breadboard looks as following:
Notes:
1.8 volt power supply, sufficient according to the HD74HC32 datasheet
1A is located at the left bottom
Vcc connected to [+] and GND connected to [-]
1Y connected to LED Anode
LED cathode connected to [-]
I tried every possible combination, with and without resistors, but I cannot get the gate to work. The LED even stays on while 1A and 1B are disconnected.
How do I get this OR gate to work as expected?
The following question looks alike, but I just can't get it to work :(
Connecting AND Gate Chip to an Integrated Circuit
