Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings
are stress specifications only and functional operation of the device at these or any other conditions above those listed in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect product reliability.

Notes:
1 When using singled-ended clock input, VTH is supplied to CLK_INTC as shown in Figure 2.
Duty cycle of singled-ended CLK_IN is measured at V_TH
2 This range of SMBus input high voltages allows the 9214 to co-exist with 3.3V, 2.5V and 1.8V
devices on the same SMBus.
