HEF4938B Overview
The HEF4938B is a dual retriggerable-resettable monostable multivibrator. Each multivibrator has an active LOW trigger/retrigger input (I0), an active HIGH trigger/retrigger input (I1), an overriding active LOW direct reset input (CD), an output (O) and its plement (O), and two pins (CTC and RCTC) for connecting the external timing ponents Ct and Rt. Typical pulse width variation over temperature range is ±0.2%.
