  • Waveform Peak Detector Reduces Data Rate to Microcomputer Speeds
    As shown in Fig. 5, these buffers are enabled with a transistor - transistor logic -(TTL) low si nal. The data are latched by 74S174 D -type flip-flops (U14, U16, and U18) to gain processing time.

    The binary form of the negative of this voltage, −SP, is inputted into the tem- perature control system as transistor - transistor logic ͑TTL͒ signals carried on 14 lines from a programmable input/output interface card of a PC ͓Fig. 10͑b͔͒. The bit settings are stored in D -type latches ͑74HC573 chips͒ that then transfer the bit settings to digital-to-analog convertor chip ͑AD7538͒.
  • Integrated Digital circuits
    The logical effort g for the logical variable d amounts to 6/3 = 2. The widths like by a locking circuit would be selected, that means in the Pull-Up- path, both p-channel- transistors have the quadruple width of an unit transistor, g = 2 would follow for the s-bundle.

  • The Quintessential PIC® Microcontroller
    • Understand how an array of D flip flops or latches can implement a register. The most popular family of logic functions was, and still is, the 74 series Transistor Transistor Logic (TTL) introduced by Texas Instruments and soon copied by all the major semi- conductor manufacturers.
