Would it be fine to use different output pull-up voltage for the channels of SN74HCS09? We are currently using SN74HCS09 with 5V Vcc.
Three of its channels will be receiving signals with 3.3V level. Output pull-up will be at 3.3V. While the other channel would also receive 3.3V levels, but with an output pull-up at 1.8V. Would this work?
Thanks in advance!
