IS

Schmitt-triggered Input

IS_5V

5V Tolerant Schmitt-triggered Input

O8

Output with 8mA sink and 8mA source

OD8

Open-drain output with 8mA sink

O12

Output with 12mA sink and 12mA source

OD12

Open-drain output with 12mA sink

PU

50uA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-

ups are always enabled. 
Note:

Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on 
internal resistors to drive signals external to LAN9514. When connected to a load 
that must be pulled high, an external resistor must be added.

PD

50uA (typical) internal pull-down. Unless otherwise noted in the pin description, internal 

pull-downs are always enabled.
Note:

Internal pull-down resistors prevent unconnected inputs from floating. Do not rely 
on internal resistors to drive signals external to LAN9514. When connected to a 
load that must be pulled low, an external resistor must be added.
