Question 3 |
When used with IC, what does he term QUAD indicate?
2 circuits | |
4 circuits | |
6 circuits | |
8 circuits |
Question 3 Explanation:
→A quad gate is an IC (integrated circuit or chip) containing four logic gates. The gates can be of any type: AND, OR, XOR, NOT, NAND, NOR, and XNOR. Within any given quad gate, all four of the individual gates are normally of the same type.
→A logic gate is an elementary building block of a digital circuit.
→A logic gate is an elementary building block of a digital circuit.
Question 4 |
When a tri - state logic device is in the third state, then :
it draws low current | |
it does not draw any current | |
it draws very high current | |
it presents a low impedance |
Question 4 Explanation:
Three Stage logic name itself implies there are 3 states of the buffer.
1. High (1)
2. Low (0)
3. High Impedance (Z)
→ High impedance means that a point in a circuit (a node) allows a relatively small amount of current through, per unit of applied voltage at that point.
→ High impedance circuits are low current, high voltage, whereas low impedance circuits are the opposite.
