Overview
The CD4098BM, manufactured by Texas Instruments, is a CMOS Dual Monostable Multivibrator. This component is designed to provide stable, retriggerable/resettable one-shot operation for various fixed-voltage timing applications. Although the CD4098BM is no longer in production, it remains relevant for understanding and utilizing similar components in current designs.
The device operates using an external resistor (RX) and an external capacitor (CX) to control the timing, allowing for a wide range of output pulse widths. It features leading-edge and trailing-edge triggering inputs, separate resets, and buffered outputs.
