The MM2708, MM2708-1 are high speed 8192 UV erasable and electrically reprogrammable EPROMs ideally suited for applications where fast turn-around and pattern experimentation are important requirements. The MM2708, MM2708-1 are packaged in a 24-pin dual-in-line package with transparent lid. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written into the devices by following the programming procedure.
