Detailed Product Description: | 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, and strive to lead the Czech Republic is short, avoid using long leads in parallel, or easy to introduce a large distributed capacitance and inductance 74HCT14D, 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 lead is too long, 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. In addition, the need to adopt some shielding, isolation measures. When operating frequency exceeding 200Mz, should use multi-layer circuit board to reduce ground impedance. MC33035DW2G crystal diode pn junction formed by 74HCT14D supply a p-type semiconductor and n-type semiconductor layer is formed on both sides of the space charge at the interface, and built a self-built electric field. When there is no applied voltage, the pn junction due to the carrier concentration difference on both sides of the drift current and diffusion current caused by self-induced electric field equal and in electrical balance. When the outside there is a positive voltage bias 74HCT14D manufacturers, external electric field and the electric field of mutual self restrain consumer action to make the carrier diffusion current increases caused a forward current. When the outside there is a reverse voltage bias 74HCT14D wholesale, the external electric field and the electric field is further strengthened self, is formed in a certain reverse voltage and the reverse bias voltage range regardless of the value of the reverse saturation current I0. When the applied reverse voltage is high to a certain extent, pn junction space charge layer in the electric field strength reaches a critical value generating carrier multiplication process, a large amount of electron-hole pairs, resulting in a large reverse breakdown current value , known as the diode breakdown. pn junction reverse breakdown Zener breakdown and avalanche breakdown of the points. 74HCT14D wholesale | Jiangsu 74HCT14D | 耀坤 technology provided by Nanjing 耀坤 Technology Limited.
