Diode Transistor Logic Component

If all the inputs X, Y, Z are driven high, the diodes in series conduct, driving the transistor into saturation. Thus output out is Low.

what is Resistor Transistor Logic Diagram
In RTL (resistor transistor logic), all the logic are implemented using resistors and transistors. One basic thing about the transistor (NPN), is that HIGH at input causes output to be LOW (i.e. like a inverter). Below is the example of a few RTL logic circuits.
A basic circuit of an RTL NOR gate consists of two transistors Q1 and Q2, connected as shown in the figure above. When either input X or Y is driven HIGH, the corresponding transistor goes to saturation and output Z is pulled to LOW.
In DL (diode logic), all the logic is implemented using diodes and resistors. One basic thing about the diode, is that diode needs to be forward biased to conduct. Below is the example of a few DL logic circuits.Diode Logic Circuit
When no input is connected or driven, output Z is low, due to resistor R1. When high is applied to either X or Y, or both X and Y are driven high, the corresponding diode get forward biased and thus conducts. When any diode conducts, output Z goes high.
Points to PonderDiode Logic suffers from voltage degradation from one stage to the next.
Diode Logic only permits OR and AND functions.
Diode Logic is used extensively but not in integrated circuits.
