Hi!
I'm seeing some issues with the level translating capability of TI's SN74TVC3306. On a single chip, i've set the reference to 3.3V and the chip's 2 outputs are driving a 244 driver. One of the output's voltage level is OK and shows a logic high of 3.3V while the other output is only coming up to around 2.8V.
Some freshly manufactured boards are showing this issue, while some are OK. What confuses me is that the 2 outputs are coming from the same TVC3306, a single reference voltage, same type of load for each output, yet different voltage level. One is used as a data output, while the other is used to provide clock.
Has anybody out there seen this before? Ideas?
Thanks!
Regards,
Joel
