The CD4538BC is a dual, precision monostable multivibrator<br />with independent trigger and reset controls. The device<br />is retriggerable and resettable, and the control inputs are<br />internally latched. Two trigger inputs are provided to allow<br />either rising or falling edge triggering. The reset inputs are<br />active LOW and prevent triggering while active. Precise<br />control of output pulse-width has been achieved using linear<br />CMOS techniques. The pulse duration and accuracy<br />are determined by external components RX and CX. The<br />device does not allow the timing capacitor to discharge<br />through the timing pin on power-down condition. For this<br />reason, no external protection resistor is required in series<br />with the timing pin. Input protection from static discharge is<br />provided on all pins.<br />自己翻译过来都不知说的什么呀?好像是一些关键的知识点我不是很明白的。能说说吗? |
