GTL2008

GTL translator with power good control and high-impedance outputs

8.

Application design-in information

(1) If 9AO needs to be HIGH before EN2 goes HIGH, a pull-up resistor is required because it is high-impedance until EN2 goes

HIGH. All other outputs, both GTL and LVTTL, require pull-up resistors because they are open-drain.
