* for my application the frequency will not be more than 50Hz.
* Wide supply range.
Can you clarify what you mean by "pulse splitter"? I'm not familiar with this term. It looks like it is used in the context of flowmeters and other sensors that output pulses, such that multiple counting devices can read the output of a single sensor.
Thank you for your reply, you are quite correct this is pulse splitter in the context of flow meters. Most Commercial off-the-shelf pulse splitters are still designed with discrete logic components, I wanted to find out if there is any component/chip that does that, perhaps with useful features like Schmitt trigger, pulse width adjustment etc. in a single component.
Or reference circuit of a simplified of a generic setup would be nice.
Your original question mentioned that the circuit needed to handle a "wide supply range". You would need to specify how wide, for both the input and output signal, and what . You would want to research the range of signals that your splitter needs to accept, what power supplies are available, and what the outputs need to do (Voltage output? open collector? solid-state relay closure?) These aspects of the design may be outside of the scope of the assistance we can provide, and you might want to consider sticking with the input / output circuitry is used in existing designs, especially if they have a proven to be reliable.
There is a family of parts that might be appropriate for the timing - the LTC6993 is a resistor-programmable one-shot that will likely be more accurate than discrete logic timing components (like 74HC221, 74HC4538 style devices.) The LTC6993 does not use external capacitors for timing. (Capacitors tend to be the dominant error source when used in timing circuitry.)
