DS25BR440: OUT+ & OUT- maximum allowable voltage and current

Lok Wei Hern

Part Number: DS25BR440

What are the withstandable voltage and current for OUT+ & OUT- pins?

Will the current be drained through the output 100 Ohm termintation when these pins are accidentally declared as inputs?

Hi lok,

DS25BR440 is a LVDS buffer. LVDS transmitter supplies about 3.5mA into the 100-ohm termination of the receiving device. Please note this current is sunk into the LVDS transmitter output structure. In other words, current returned path goes through the output structure of the LVDS buffer. As such, excess current may damage LVDS output structure. Please note link below discussing this in more details:
