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

DESCRIPTION

The HCF4538B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

The HCF4538B dual precision monostable

multivibrator provides stable retriggerable/

resettable one-shot operation for any fixed voltage

(reset propagation delay) are independent of R

and C . Precision control of output pulse width is

achieved through linear CMOS techniques.

Leading edge triggering (+TR) and trailing edge

triggering (-TR) inputs are provided for triggering
