Diode Transistor Logic Truth Table. If any input a or b or c is 1 the output will be 1. Figure 2 truth table of and gate.
Figure 3 a gives the circuit symbol and boolean expression for nor gate while figure 1 b gives the two input truth table. The circuit above is a 3 input diode transistor logic dtl gate. Which type of logic gate does this circuit represent.
Figure 2 truth table of and gate.
This is the definition of a logic or. Or gate can be realized by diode resistance logic drl or by transistor transistor logic ttl. If any input a or b or c is 1 the output will be 1. Positive nor gate may be implemented by putting transistor not gate at the output of a diode or gate as shown in figure 3.
