Lead Temperature Range (soldering, 10 Seconds).................................................................... +325^°C
Positive Voltage on any pin with respect to Ground .............................................................. VDD + 0.3V
Negative Voltage on any pin with respect to Ground..................................................................... -0.3V
Maximum V +TBDV DD ...................................................................................................................................................................................................................................
The above is a stress rating only. Stresses greater than the ones listed above could damage the
device permanently. Device operation outside of the above stated conditions is not recommended.
Note: When powering this device from a laboratory or system power supply, it is important that the
Absolute Maximum Ratings are not exceeded. Some power supplies exhibit voltage spikes on their
outputs when the AC power is switched on or off. Also, voltage transients on the AC power line may
appear on the DC outputs. If such possibilities exist, a clamping circuit should be used.

* _{5mA per LED lit. LEDs’ activity light pulses are stretched into milliseconds (a lot longer than the chip}
active time). As the chip drops back to the idle state immediately at the end of a TX or RX, the actual
time-averaged current consumption will be between the Busy and Idle numbers.
