APPLICATION NOTES
m P’s with Bidirectional Reset Pins
The RESET output can be pulled low by processors like
the 68HC11 allowing for a system reset issued by the
processor. The maximum pullup current that can be sourced
by the CAT705 & CAT706 1.5 mA (and by the CAT706
T/R/S is 800 m A) allowing the processor to pull the output
low even when the CAT70x is pulling it high.
Power Transients
Generally short duration negative ? going transients of less
than 2 m s on the power supply at V RST minimum will not
cause a reset condition. However the lower the voltage of the
transient the shorter the required time to cause a reset output.
These issues can usually be remedied by the proper location
of bypass capacitance on the circuit board.
Output Valid Conditions
The RESET output uses a push ? pull output which can
maintain a valid output down to a V CC of 1.0 volts . To sink
current below 0.8 V a resistor can be connected from
RESET to Ground (see Figure 11.) This arrangement will
maintain a valid value on the RESET output during both
power up and down but will draw current when the RESET
output is in the high state. A resistor value of about 100 k W
should be adequate in most situations to maintain a low
condition valid output down to V CC equal to 1.0 V.
