CD4538BCN – FSC

Overview

The onsemi CD4538BCN is a high-performance dual monostable multivibrator designed for precise pulse generation and timing applications. Its key operational characteristic lies in its ability to produce a single, fixed-width output pulse in response to a triggering input edge, offering a propagation delay of 100 ns. A critical design consideration when utilizing this CMOS device is managing the trade-off between power consumption and switching speed; while it excels in low-power environments, achieving optimal timing accuracy necessitates careful consideration of supply voltage and capacitive loading, which can impact the effective pulse width and trigger sensitivity.
