SI2457-C-FTR Overview
There is a possibility of mounting PCBs on Surface Mount.Package cost is one of the characteristics of the 24-TSSOP (0.173, 4.40mm Width).In order for 3V~3.6V Supply Voltage to function normally, 3V~3.6V Supply Voltage must be present.Packing materials Tape & Reel (TR) are used.Based on the Base Part Number SI2457, related parts can be identified.It is connected by a 24-pin.A variety of 24 pins can be used depending on the application.The program terminates at 24 points.It is mounted on a Surface Mount-shaped stand.In order for 70°C to be higher than Operating Temperature, it should be lower.During operation, it should increase the temperature of 0°C.The voltage at 3.3V is required for this system to function.Performance-cost ratio makes this series an excellent value.A sufficient supply current is required by 3.3V so that it can function properly.Its ability to operate with 26mA supply voltage makes the device a great choice for many different applications.
