Since this method carries some risk to rip pads off the PCB, I'd like to suggest a different desoldering method, which can be applied whenever the old chip does not need to be salvaged (for it is cheap to replace or known to be broken anyway):

You can use a scalpel or *sharp* cutter knife and simply cut off the pins next to where they come out of the plastic case (using the chip's case as a guide). Afterwards, the pins can be desoldered from the pads one after another without any risk to apply too much heat or force to the pads. This may sound "brutal" at first, but it is actually quite easy to do and very reliable.
