I´m trying to select a voltage level translator for my gc864 serial port,
there are several choices which mainly fall into two categories, VLT for
Open Drain types of outputs like i2c or SPI and VLT for Push-pull type of outputs
which one is used on the GC864 serial port and trace pins?
Also, should I use pull-up´s for these data lines?
In the Hardware users guide there are some examples with an open drain buffer used
for the output ( TC7SZ07AE) with an pull up and another buffer the TC7WZ34FK for the input, both are from toshiba and are discontinued. the first one is a single port and the latter is a 3 port . I wonder if someone could point out other commercial models used
in any project.
The conversion leves I´m working with are 2.8V to 3.3V
