TTL Circuit Analysis Flashcards
Shottky Diode protects the input circuit from what?
from negative voltages that are connected accidentally or from voltages arising from oscillations known as ringing
What does biasing refer to?
it simply means that external voltage is applied across the two terminals of the diode.
What is forward biasing?
When the positive terminal of the battery is connected to the p-type material and the negative terminal of the battery is connected to the n-type material
What is reverse biasing?
When the positive terminal of the battery is connected to n-type material and the negative terminal of the battery is connected to p-type material
An input is defined as High when…
D1 is reversed biased and shut off
An input is defined as Low when…
diode D1 is turned on

Circuits define what levels?
H and L Levels
The 74LS00 is a what gate?
a “nand” gate
a 74LS05 is a what?
an inverter
