need small PAL with SR latch

Hi,
I need a small prgramable logic device with a couple of SR latches,
however they all seem to have D types or other type of latch on the macro
cell with a global clock/set/reset, exept for some of the realy big ones.

Ive looked through all of the ones that Farnell sell, and although I
could obviously feed back an output to make an SR latch this wouldnt be
ideal, any one know if there are any like this ?

Only needs a dozen gates or so to do the job, could do with being fast
as posible and in circuit programable etc.
