*EL5175 and EL5375 -- Model Rev. A 10/20/2003
*low power, wide bandwidth differential receiver---550MHz for gain of 1
*The AC response for this model is based on Vs=+/-5V and RL=500
*SR and open loop gain are modeled. The enabled/disabled function is not modeled.
*The output short circuit current is not modeled
