557GI-03LF Overview
An accompanying case is included. There are 16 terminations in it. The part provides a voltage of 3.3V volts. The peak reflow temperature is used to run 260. 1 are present on the device. normaloperation has a maximum frequency of 200MHz. Currently, there are 2003 publications of the part. The Surface Mount mounting method is recommended. There are 16 pins on this device. The board has 16 pins. The minimum working temperature of this device cannot be lower than -40°C. There should be a temperature below 85°C during operation. 3.3V should be the supply voltage. A 2 output can be maintained on the device. According to the supply voltage, this part operates at 3.63V. In order to maintain a device's supply voltage greater than 2.97V. When the supply current is set to 78mA, this part can operate. An excellent efficiency can be achieved when working at a frequency of 25MHz.
