Typicals are at TA = 25°C and represent most likely parametric norm. Standby current typ. is measured with VCC = 3.3 V. Timing specifications are tested at logic levels of VIL = 0.8 V for a falling edge and VIH = 2.1 V for a rising edge. 2. Operation at 5.5 V is guaranteed by design, not production tested. 3. Recommend use of 100 kW pullup resistors for all open−drain outputs from the ADM1033. 4. Guaranteed by design, not production tested. 5. SMBus timeout disabled by default. See the SMBus section for more information. |
