SN74LVC1G32 VOH/VOL at 3.3V supply

Hi Team,

Would you let me know SN74LVC1G32 VOH/VOL at 3.3V Vcc condition?
Vcc 3V VOH/VOL spec existing in datasheet and I think 3.3V spec is same or almost similar, however customer requested exact spec at 3.3V supply condition.
Would you provide the spec to customer?
Thank you.

Best Regards,
Jade

    Hi Jade!

    The output voltage depends on the current the device has to sink or source. Look at this table:

    If you do not sink or source currents higher than 100µA, the output voltage is about 100mV away from the supply rails - and this is the case for a supply voltage from 1.65 to 5.5V (full recommended range), so your 3.3V is covered as well. If you have higher currents, the voltage drop (high-level) or raise (low-level) will increase.

    Thanks for the reply Dennis, you are right.

    Hi Jade ,

    If its not specified on the datasheet we cannot guarantee a spec to the customer. As you mentioned , the 3V specs would closely represent the performance of 3.3V .
    The LVC characterization info can also give a good insight into the operation of 3.3V condition.
