hi:
im trying use dac ltc7545a arduino reason not working dac 0808. think might related wr , cs pins, pins for???

cs chip select. tells chip it's being addressed... if have ram, rom, dac, etc. on data bus, 1 chip should selected @ time. if there's nothing else sharing data lines, may able tie permanently low.
the wr (write line) means writing data chip. (or, can think of telling chip "read"... i'm writing, need read... i'm talking, need listen...) means, "ok.. correct data on data bus , ready use." when data on data bus changing, invalid/unknown short period of time , it's important make sure data stable before activating write-line. example, let's counting-up 011 (3) 100 (4). there may short period of time when have 111 (7).
