Notice that the transistors in this diagram are drawn so that current flows from top to bottom, the usual convention in circuit diagrams. In bipolar transistors, current flow is usually in the direction of the arrow forming the emitter symbol. This is why the pnp transistor is drawn with its...
The circuit diagram of a transistor in the cut-off region is as shown in the below figure. Cut-off Mode of Transistor NPN Transistor Pinout The transistor has three leads; collector (C), Emitter (E), and Base (B). In most of the configurations, middle lead is for Base. To identify...
The device contains at least two JFET transistors, connected in series (J1-J6) (field p-n junction FETs). The lowest of these (J1) is connected to the first output (1) either directly or in cascade via a control switch (M). The device also contains at least one complementary JFET (...
Transistors are semiconductors, meaning they can conduct electricity. A transistor can amplify the electric current, or in other words, it can increase the initial electric current. Transistors can also function as switches that open or close a circuit in an electronic device. View...
The circuit diagram for a single two-input NAND gate implemented in TTL is shown in Fig. 9.3. Although it is not immediately obvious it does build on the DTL design of Fig. 9.2(a). The diodes D1, D2 and D3 have been replaced by a single transistor (T1) that has a multiemitter ...
The Common Emitter Amplifier CircuitIn this type of configuration, the current flowing out of the transistor must be equal to the currents flowing into the transistor as the emitter current is given as Ie = Ic + Ib.As the load resistance ( RL ) is connected in series with the collector, ...

Transistors provide switching, turning on or off in response to input signals. Resistors limitcurrentand help optimizevoltagelevels for the transistors. Diodes ensure current flows in only one direction, helping to stabilize the circuit. Figure 1. This diagram shows a two-input TTL NAND gate with...
1. A small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier, detector, or switch. 2. Any of various devices serving the same purpose but employing a different technology: an optical transistor. 3. A transistor radio....
The circuit diagram above uses NAND gates within the IC. So select switch A to activate the circuit then you can notice that both the LEDs in the circuit will turn off. When the output is low, then the input should be high. After that, select the switch B then both the LEDs will tu...
