VOLTAGE DETECTOR

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.

FEATURES

APPLICATIONS

(1) As Control Circuit of Battery-Backed Memory Units.

(2) As Measure Against Erroneous Operations at Power Supply ON-OFF Time.

(3) As Measure Against System Runaway at Instantaneous Break of Power

(4) As Resetting Function for the CPU-Mounted Equipment, such as Personal

Current Consumption is Low. I
