hi all,
i'm doing this project in voice playback and recording.i'm using
PIC18F452 and ISD2560 voice chip.
do i need to put a latch between th epic and isd chip? and if so, which
one is best suited for the same?
thanks

This would be a good question for sci.electronics.basics.

I cannot see why you'd need a latch unless you're running out of GPIO pins
on the PIC due to other requirements you've not mentioned.
