Integrated Circuits

  • Linear ICs begin with the letter "T", e.g. TAA570 Limiter-Amplifier and FM Detector.
  • Logic ICs begin with the letter "F".
    • The FJ family is TTL (e.g. the FJH231 is a Quadruple 2-input Open-collector NAND gate equivalent to the SN7401)
    • The FC family is DTL
    • The FD family is MOS.
  • Mixed analog/digital ICs begin with the letter "U", e.g. UAA180 LED bargraph A/D and driver.
FCH171 // \ \__ serial number,gives the count and type of gates for example // \___ H=gate ("Combinatorial circuit") J=flip-flop K=monostable Q=RAM R=ROM etc. FC=DTL FD=MOS FJ=TTL

Unfortunately the serial number does not specify the same type of gate in each family, e.g. while an FJH131 is a Quadruple 2-input NAND gate (like the 7400), an FCH131 is a Dual 4-input NAND gate.

Famous quotes containing the words integrated and/or circuits:

    “Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
    —Talcott Parsons (1902–1979)

    “The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.”
    —Robert M. Pirsig (b. 1928)
