MK1491E-14RLFTR OverviewThere is a Tape & Reel (TR) package that contains it. 28-SSOP (0.154, 3.90mm Width) is included in the case. Clock program is recommended to mount using type Surface Mount. The device contains 1. In normaloperation, the maximum frequency is 75MHz. The operating temperature is varied over a range of 0°C~70°C. Clock program is possible for the component to supply a voltage of 3V~3.6V. Its primary purpose is Intel CPU, OPTi Firestar/Firestar+ chipset. As the output, Clock should be used. Searching for information is made easier by using the MK1491-14 part number as the base number.
