Transistors as Digital Switches: Intro to Logic Gates Circuits that really count
My sound’s laid down by the (digital) underground…
Operation in Saturation and Cutoff
Binary/Digital Representation Digital “ 1” = high = +Vcc Digital “ 0” = low = 0 V
Inverter (NOT logic gate)
NAND gate +Vcc
NOR gate
Design an OR gate A B Y 0 0 0 1 0 1 1 1
And now, your joke of the day l There are only 10 types of people in the world. Those who understand binary, and those who don’t.
Exclusive OR (XOR) out
