Product Summary

The HEF4538BP is a dual retriggerable-resettable monostable multivibrator. The HEF4538BP has an active LOW trigger/retrigger input (n A), an active HIGH trigger/retrigger input (nB), an overriding active LOW direct reset input (nCD), an output (nQ) and its complement (nQ), and two pins (nREXT/CEXT, and nCEXT, always connected to ground) for connecting the external timing components CEXT and REXT. Typical pulse width variation of the HEF4538BP over the specified temperature range is ±0.2 %. The HEF4538BP may be triggered by either the positive or the negative edges of the input pulse and will produce an accurate output pulse with a pulse width range of 10 µs to infinity. Application areas of the HEF4538BP include Automotive and Industrial.
