The EPROM-based EP220 and EP224 devices feature a flexible I/O
architecture and implement 150 usable (300 available) gates of custom
user logic functions. EP220 and EP224 devices can be used as upgrades for
high-speed bipolar programmable logic devices (PLDs) or for 74-series LS
and CMOS (SSI and MSI) logic devices in high-performance
microcomputer systems.
