We are using this Level Shifter for the communication between the micro controller and an ASIC.
On the most recent PCB's when the ASIC isn't used e.g. no communication, the current consumption is between 10mA and up to 35mA. But on the prototypes we made 2 years ago it is below 1mA. Since the current consumption of the PCB is quite important, this causes some problems.
There is a 51kOhm pull up resistor on the enable pin.
