Hysteresis Voltage is Provided. 50mV Typ.

Reset Signal Generation Starting Voltages :

Taping Type is also Available.

APPLICATIONS

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

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

(3) As Measure Against System Runaway at Instantaneous Break

of Power Supply etc.

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

such as Personal Computers, Printers, VTRs and so forth.
