... The HCC4538B (extended temperature range) and HCF4538B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in-line plastic or-ceramic package and plastic micro package. The HCC/HCF4538B dual precision monostable multivibrator provides stable retrigger- able/resettable one-shot operation for any fixed- voltage timing application. An external resistor (R ...

... HCC/HCF4538B prevent output pulses when power is turned on. An unused RESET input should be tied to V ever entire section of the HCC/HCF4538B is not used, its inputs must be tied to either V (see table 1). In normal operation the circuit triggers (extends the output pulse one period) on the appli- cation of each new trigger pulse. For operation in the non-retriggerable mode connected to – ...
