TECHNICAL DATA

KIA7419P/F~KIA7445P/F

BIPOLAR LINEAR INTEGRATED CIRCUIT

Revision No : 2

VOLTAGE DETECTOR

This IC series is usable for the CPU system of all types and wired

logic system as it has the function of detecting the power supply voltage

at the time of initial resetting after switching the power supply on and

after instantaneous break in power supply voltage there-by accurately

resetting the system this particular series has especially been designed

as the high resetting output type.
