SN751701: VOL & VOH spec data

Jin Ikeda

Part Number: SN751701

Hello Team,


My customer is going to use our SN751701 as RS232C.

Then engineer wants to know below points for SN751701 driver side. Could you provide those info ?

(1) Minimum VOL & maximum VOH voltage under 25degC condition. (Unfortunately our data sheet doesn't have those.)
(2) Effect of temperature on the VOL and VOH (Performance trend at high and low temperatures compared to Ta25degC).
(3) VOL & VOH data when Vcc is 13.5V.  (I guess we don't have such a data. In that case, Can we suggest estimation value compared with Vcc = 12V) ?.


Best Regards,
Jin

    Jin,

    Due to the age of this part, unfortunately we do not have this information to provide. The part is characterized with the conditions specified in the datasheet.

    (1) Minimum VOL & maximum VOH voltage under 25degC condition. (Unfortunately our data sheet doesn't have those.)

    This is an interesting request. What is the application that requires this information? The customer can use VCC as the limit.

    These values will be larger than the values at the values at VCC = 12 V. Though we do not have this characterization data to provide or guarantee, my hand calculations lead me to estimate that the typical value for VOL would be around -11 V while the typical value for VOH would be around +11 V.

    I hope this is helpful.

    Best,
