The CD4538BC is a dual, precision monostable multivibrator
with independent trigger and reset controls. The device
is retriggerable and resettable, and the control inputs are
internally latched. Two trigger inputs are provided to allow
either rising or falling edge triggering. The reset inputs are
active LOW and prevent triggering while active. Precise
control of output pulse-width has been achieved using linear
CMOS techniques. The pulse duration and accuracy
are determined by external components RX and CX. The
device does not allow the timing capacitor to discharge
through the timing pin on power-down condition. For this
reason, no external protection resistor is required in series
with the timing pin. Input protection from static discharge is
provided on all pins.
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？ |
