542-DPK 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 156MHz. In this case, it is set up as Surface Mount. Electrical components classified as Fanout Buffer (Distribution), Divider are classified as such. The clock switch should operate with a voltage of 3V~5.5VV. As a result, it produces 3-State, CMOS. The ICS542 family contains it.
