Frequently the reset controller will be deployed on a PC board that provides a peripheral function to a system.
Examples might be modem or network cards in a PC or a PCMCIA card in a laptop. In instances like this the peripheral
card may have a requirement for a clean reset function to insure proper operation. The system may or may not provide
a reset pulse of sufficient duration to clear the peripheral or to protect data stored in a nonvolatile memory.
The I/O capability of the RESET pins can provide a solution. The system
s reset signal to the peripheral can be fed
into the S24042/43 and it in turn can clean up the signal and provide a known entity to the peripheral
s circuits. The
figure below shows the basic timing characteristics under the assumption the reset input is shorter in duration than
t
PURST
. The same reset output affect can be attained by using the active high reset input.
When planning your resistor pull-up and pull-down values, use the following chart to help determine min. resistances.
