SA56606-XXCMOS system reset
GENERAL DESCRIPTION
The SA56606-XX is a CMOS device designed to generate a reset
signal for a variety of microprocessor and logic systems. Accurate
reset signals are generated during momentary power interruptions
or whenever power supply voltages sag to intolerable levels. An
Open Drain output topology is incorporated for adaptability to a wide
variety of logic and microprocessor applications. Several reset
threshold versions of the device are available.
The SA56606-XX is available in the SOT23-5 surface mount
package.
