Activity: TTL inverter and NAND gate [Analog Devices Wiki] The schematic of a Transistor Transistor Logic (TTL) inverter is shown in figure 1. This circuit overcomes the limitations of the single transistor inverter circuit. The basic TTL inverter consists of three stages. A current steering input, a phase splitting stage and an output driver stage. Theory of TTL Inverter and its Transfer Characteristic Figure: Circuit Diagram and Transfer Characteristic of a TTL Inverter C) The diode D , serves to raise the effective V BE of T 4 that allows T 4 to be turned OFF before T 3 turns ON fully. It prevents large surge currents from flowing whenever both transistors conduct during transitions among logic states.

List of 7400 series integrated circuits The following is a list of 7400 series digital logic integrated circuits.The original 7400 series integrated circuits were made by Texas Instruments with the prefix "SN" to create the name SN74xx. Due to the popularity of these parts, other manufacturers released pin to pin compatible logic devices which kept the 7400 sequence number as an aid to identification of compatible parts. Transistor–transistor logic TTL was invented in 1961 by James L. Buie of TRW, which declared it, "particularly suited to the newly developing integrated circuit design technology."The original name for TTL was transistor coupled transistor logic (TCTL). The first commercial integrated circuit TTL devices were manufactured by Sylvania in 1963, called the Sylvania Universal High Level Logic family (SUHL). Fan out of TTL inverter circuit | All About Circuits Here is my attempt to find fan out for TTL inverter circuit.
