HCF4098B

The HCF4098B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages. The HCF4098B dual precision monostable multivibrator provides stable retriggerable/ resettable one-shot operation for any fixed voltage timing application. An external resistor (R_X) and an external capacitor (C_X) control the timing for the circuit. Adjustment of R_X and C_X provides a wide range of output pulse widths from the Q and Q terminals. The time delay from trigger input to output transition (trigger propagation delay) and the time delay from reset input to output transition (reset propagation delay) and the time delay from reset input to output transition (reset propagation delay) are independent of R_X and C_X. Leading edge triggering (+TR) and trailing edge riggering (-TR) inputs are provided for triggering from either edge of an input pulse. An unused +TR input should be tied to V_SS. An unused -TR input should be tied to V_DD . A RESET (on low level) is provided for immediate termination of the output pulse or to prevent output pulses when power is turned on.
