#TOTEM POLE OUTPUT WHAT IS PC#
The first PC like Kenbak-1 was used Transistor-Transistor Logic for its CPU as an alternate of a microprocessor. Generally, functions in a single package range from logic gates to a microprocessor. Usually, each TTL chip includes hundreds of transistors. The Transistor-Transistor Logic was applied to many bipolar logic generations by slowly improving the speed as well as power utilization over about two decades. The one and only one manufacturing company like IBM was launched non-compatible circuits using TTL for their own use. The compatible parts of the 7400 families launched by Texas instruments were designed by several companies like National Semiconductor, AMD, Motorola, Intel, Fairchild, Signetics, Intersil, Mullard, SGS-Thomson, Siemens, Rifa, etc. After that, the 7400 series was launched through a narrower range in the year 1966. In 1963, the manufacturing first commercial TTL devices were designed by “Sylvania” known as SUHL or ‘Sylvania Universal High-Level Logic family’.Īfter the Texas instruments engineers launched the 5400 series ICs in the year 1964 with the range of military temperature, then the Transistor-Transistor Logic became very popular. The actual name of this TTL is TCTL which means transistor-coupled transistor logic. It is suitable for developing new integrated circuits. The TTL or Transistor-Transistor Logic logic was invented in the year 1961 by “James L.
