When powering this device from laboratory or system power supplies, it is important that the absolute
maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage
spikes on their outputs when AC power is switched on or off. In addition, voltage transients on the
AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp
circuit be used.
This rating does not apply to the following pins: XI, XO, EXRES, USBRBIAS.
This rating does not apply to the following pins: EXRES, USBRBIAS.
0oC to +70oC for commercial version, -40oC to +85oC for industrial version.
+/-8kV for LAN9500/LAN9500i, +/-5kV for LAN9500A/LAN9500Ai
Performed by independent 3rd party test facility.
*Stresses exceeding those listed in this section could cause permanent damage to the device. This is a stress rating
only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Functional
operation of the device at any condition exceeding those indicated in Section 8.2, "Operating Conditions**", Section 8.4,
"DC Specifications", or any other applicable section of this specification is not implied. Note, device signals are NOT 5
volt tolerant unless specified otherwise.
8.2 Operating Conditions**
Supply Voltage (VDD33A, VDD33BIAS, VDD33IO)............................................................................ +3.3V +/- 300mV
Ambient Operating Temperature in Still Air (TA).............................................................................................. Note 8-4
**Proper operation of the device is guaranteed only within the ranges specified in this section.
8.3 Power Consumption
This section details the power consumption of the device as measured during various modes of operation. Power con-
sumption values are provided for both the device-only, and for the device plus Ethernet components. Power dissipation
is determined by temperature, supply voltage, and external source/sink requirements.
Note: All current consumption and power dissipation values were measured at VDD33IO and VDD33A equal to
3.3V.
