HEF4938B Datasheet Dual precision monostable multivibrator

Manufacturer: NXP Semiconductors

General Description

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 complement (O), and two pins (CTC and RCTC) for connecting the external timing components Ct and Rt.

Typical pulse width variation over temperature range is ±0.2%.
