74HC4538 Dual retriggerable precision monostable multivibrator Rev. 6 - 16 July 2021 Product data sheet 1. General description The 74HC4538 is a dual retriggerable-resettable monostable multivibrator. Each multivibrator has two trigger/retrigger inputs (nA and nB), a direct reset input (nCD), two plementary outputs (nQ and nQ), and two pins (nREXT/CEXT and nCEXT) for connecting the external timing ponents CEXT and REXT. Typical pulse width variation over temperature range is ± 0.2 %. The device may be triggered by either the positive or the negative edges of the input pulse. The duration and accuracy of the output pulse are determined by the external timing ponents CEXT and...
