SA56606-XX

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.
