cd4017中文资料内容说明(国外英文资料) CD4017 Chinese data description CD4017 Chinese Data Description: CD4017 is a 5 bit Johnson counter, with 10 decoding output, CP, CR, INH input. Shizhongshu A Schmitt trigger input end of pulse shaping function, no restrictions on the rise and fall times of the input clock pulse. INH Low, counter counts in the rising edge of the clock; on the contrary, the counting function is invalid. When CR is high, the counter is cleared. Johnson counter, provides fast operation, 2 input decoding strobe and decoding output without burr. Anti lock strobe, ensure Count the correct order. The decoding output is generally low level, maintain a high level only in the corresponding clock cycle. In each of the 10 The clock input CO signal cycle to complete a carry, and as a lower ripple clock multistage counting chain. CD4017 provides 16 lead multilayer ceramic dual in line (D), sealing ceramic dual in line (J), plastic dual in line (P) And the ceramic chip carrier (C) package 4. Terminal function symbols CO: carry pulse transmission yuan CP: clock input CR: clear end INH: no end The count of Q0-Q9 pulse output VDD: positive power supply VSS: anti shake touch switch circuit to CD4017. This is a trigger circuit for a practical, easy to use, and various combinations of temperature control circuit, light control, voice control, RF remote control. Just take these signals to the CD4017 end of the CP. This circuit uses a decimal counter CD4017, output Y2 and reset RST is 14 to two feet every time the count pulse is reset. Its working principle is 220 volts alternating current through the step-down transformer, D1-D4 rectifier, C1 filter +9V DC voltage. C3 R2, a power on reset circuit, reset CD4017 Y0 output high level Y1 and Y2 output low turn-on transistor V. Relay, the normally open contact with electrical appliances. K is pressed, C2 rapid discharge, 14 foot pulse rising edge trigger, CD4017 count, Y0 output low, Y2 still maintains a low level. The triode V cutoff re
