Looking for a one shot IC, that will produce and complete the predetermined output pulse (about 15ms) despite the input, that gave rise to said pulse, held constant. The reset needs to be accomplished once the input changes its state again. The input is a footswitch that may remain actuated beyond the pulse duration. Retriggering during the pulse is not allowed.
I found a chip that in the data sheet perfectly describes the desired action in, for example, Maxim's Microprocessor Supervisory chips (with manual reset capability), but the SMD package is too small.
There are at least two PDIP chips named Monostable Multivibrator but mention nothing of the case where the input is held throughout the pulse duration, or whether changing the input state back to where it was will prepare the chip for the next event. They are:
Any pointers will be greatly appreciated.
