The 2708-35, 2708-45 and 27L08-45L are ultra-violet light-erasable, electrically programmable read only memories. They have 8,192 bits organized as 1024 words of 8-bit length. The devices are fabricated using N-channel silicone-gate technology for high speed and simple interface with MOS and bipolar circuits. All inputs (including program data inputs) can be driven by Series 74 TTL circuits without the use of external pull-up resistors. Each output can drive one Series 74 or 74LS TTL circuit without external resistors. The data outputs are three-state for OR-tying multiple devices on a common bus.
These EPROMs are designed for high-density fixed-memory applications where fast turn around and/or program changes are required. They are supplied in a 24-pin dual-in-line ceramic cerdip (JL suffix) package designed for insertion in mounting-hole rows on 600-mil (15.2 mm) centers. They are designed for operation from 0 to 70 °C.
