SEMICONDUCTOR KIA7419P/F~KIA7445P/F
TECHNICAL DATA
BIPOLAR LINEAR INTEGRATED CIRCUIT
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.
FEATURES
·Current Consumption is Low. ICCL=30μA Typ.
ICCH=300μA Typ.
·Resetting Output Minimum Guarantee Voltage is Low 0.8V Typ.
·Hysteresis Voltage is Provided 50mV Typ.
·Reset Signal Generation Starting Voltages:
KIA7419P/F 1.9V Typ. KIA7433P/F 3.3V Typ.
