referring to mcHF schematics sheet 4/8 LPF switching circuit ... there is R31-R34 which is a pull up resistors for the output of U14 the resistance of these resister are 27ohm .... that's a 180mA of current through the U14 ... is that ok ?? or I'm missing some thing ?

27 Ohm will draw more than 180mA, but ok for few mS pulse.
