MK74CB218
DUAL 1 TO 8 BUFFALO™ CLOCK DRIVER
The maximum speed at which the chip can operate is limited by the power dissipation in the package. Graph 1
shows the operating frequency plotted against load capacitance per pin for a die temperature of 125°C. This is at
VDD = VDDA = VDDB = 3.3 V, 70°C and with 33Ω series termination resistors.The termination resistors are
essential because they allow a large proportion of the total power dissipated outside the package. Reducing or
eliminating the series termination will cause an increase in die temperature. It is not recommended to operate the
chip at die temperatures greater than 125°C. Also note that the load capacitance per pin must include PC board
parasitics such as trace capacitance.
If not all outputs of the chip are used, it is possible to operate the chip faster with larger loads. Consult ICS for your
specific requirement.
