Intersil ICL7673 is a conventional method of switching to a spare power supply with unique performance advantages with unique performance advantages. This ICL7673 is a low -cost exchange solution refers to the system between the two power supply; the main power supply and battery backup. The main application is to maintain the switch in the CMOS RAM memory system in the CMOS RAM memory system and there are real time clocks. In many applications, this circuit will represent low insert voltage loss and loading between the power supply. The circuit has low -current consumption, wide working voltage range, and leakage low input. Which power supply can be connected to the available logic output indicator, you can also use the power switch capacity of the circuit to drive the external PNP transistor.

Lead -free PDIPS can be used for only the processing of pelvic welds. They are not used to process applications. Note: Intersil lead+annealing products use a special lead -free material group; mold/mold connection material and 100%matte tin plating board final decoration, comply with ROHS standards compatible with SNPB and lead -free welding operations. Lead-leading products are classified as MSL at the time of lead-free peak return welding to the temperature IPC/JEDEC J standard -020 that MSL meets or exceeds the lead-free requirements.
