I am working on a project that uses a PIC to operate 3 logic level HEXFET's
(IRLIZ44N & IRLD014) that is driving me crazy.  I was under the impression
that logic level HEXFET's would (when +5V is applied to the gate) would open
up an pass whatever voltage was on the drain to the source (within the
limits of the device).  Ain't happening.  All I get is 6 - 7 v through the
device, with 24vdc on the drain.  And yes, I do have the gate, drain, source
pins correctly identified.  I have tried high side, low side and would try
third side if I knew how.

Basic circuit is
                +24vdc
              |
                Drain
 +5V------Gate
                Source
              |
           24 vdc relay coil
              |
             GND

To date I have not even put the PIC in the circuit, but rather just fed 5v
from the power supply.
Any ideas or help would be greatly appreciated - I am beginning to doubt my
manhood!
Thanks
David
