LTC6957IMS-4#PBF Overview
12-TSSOP (0.118, 3.00mm Width) case is available for the cut smart buffer. In case Tube, the cut smart buffer is available. Normal operation has a maximum value of 300MHz. A total of 12 terminations have been found in it. The supply voltage of 3.3V is capable of providing high efficiency. If this is the case, it will be mounted as Surface Mount. This electronic part is classified as Fanout Buffer (Distribution). If you wish to ensure reliable performance, you should set the temperature to -40°C~85°C. In general, it should be able to work with a power source of 3.15V~3.45V volts. On this board, there is a pin count of 12. Buffer IC is CMOS that is output. The structure belongs to the LTC6957 family of structures.
