Description
Manual Reset Input. MR can be driven from TTL/CMOS logic or from a manual Reset switch. This input, when
floating, is internally pulled up to V CC with 50 k W resistor.
Supply Voltage: C = 100 nF is recommended as a bypass capacitor between V CC and GND.
Ground Reference
Power Fail Voltage Monitor Input. When PFI is less than 1.25 V, PFO goes low. Connect PFI to GND or V CC when
not used.
Power Fail Monitor Output. When PFI is less than 1.25 V, it goes low and sinks current. Otherwise, it remains high.
Non?connective Pin
Active Low RESET can be triggered by V CC below the threshold level or by a low signal on MR. It remains low for
200 ms (typ.) after V CC rises above the reset threshold.
Active high RESET output the inverse of RESET one.
