IC and lead away from the pulse voltage source should be set as far away from the location of pulsed high voltage integrated circuits, high-frequency devices. Integrated circuits and associated connecting lead wires as short as possible, in the inevitable long-term to join the overvoltage protection circuit, especially automotive tape recorders installed should pay more attention. When the CMOS circuit wiring, external components should be connected as close to the pin Seiko, Seiko McNair short lead strive semiconductors, avoid using long leads in parallel, or easy to introduce a large distributed capacitance and inductance, easy to form an LC oscillator. The solution is to train people in the input side 10KΩ resistor. When CMOS circuits for high-speed, pay attention to the circuit structure and PCB design. Output leads long Nanjing Seiko dealers, prone to "ring" phenomenon. Cause waveform distortion. Due to belong to the high-speed ECL digital integrated circuits, it is necessary to consider the "crosstalk" and other special problems exist in the signal line "reflection" and between adjacent signal lines, if necessary using transmission lines (such as coaxial cable), and to ensure that the transmission line impedance matching. Also Seiko prices, the need to adopt some shielding, isolation measures. When operating frequency exceeding 200Mz, should use multi-layer circuit board to reduce ground impedance. MC33035DW2G 1958 US Texas Instruments Inc. (TI) invention of integrated circuits (IC) since, with the development of silicon planar technology, the 1960s has invented an important integrated bipolar and MOS type two circuit, it marks the era of tubes and transistors manufactured by electronic machine quantitative and qualitative leap occurred, creating an unprecedented new industry integrated circuit industry has strong penetration and vitality. Recalling the course of development of the integrated circuit, we can see that since the invention of integrated circuits has been 40 years, "from the integrated circuit is integrated into the system." This sentence is for IC products from small-scale integrated circuits (SSI) to today's VLSI ( The best summary of ULSI) of the development process, namely the development of the integrated circuit products experienced a process from the traditional board system (System-on-board) to system-on-chip (System-on-a-chip) in. In the course of history, the world's IC industry to meet the needs of the development of technology and the market, the industrial structure has undergone three changes. 74HCT08D Nanjing Seiko dealers, Nanjing Seiko, 耀坤 technology provided by Nanjing 耀坤 Technology Limited.
