ICS621MIT Overview
There is a case of 8-SOIC (0.154, 3.90mm Width) in which it is packaged. Tape & Reel (TR) is the form in which it is packaged. It is recommended that the maximum value for normal operation is 200MHz. In this case, it is set up as Surface Mount. Electrical components classified as Fanout Buffer (Distribution) are classified as such. It is recommended to set the temperature to -40°C~85°C in order to ensure reliable performance. The clock switch should operate with a voltage of 1.14V~1.89VV. As a result, it produces LVCMOS. The ICS621 family contains it.
