The intei® 2716 is a 16,384·bit ultraviolet erasable and electrically programmable read-only memory (EPROM). The 2716 operates from a single 5·volt power supply, has a static standby mode, and features fast single address location program- ming. It makes designing with EPROMs faster, easier and more economical.

The 2716, with its single 5-volt supply and with an access time up to 350 ns, is ideal for use with the newer high performance +5V microprocessors such as Intel's8085 and 8086. A selected 2716-5 and 2716-6 is available for slower speed applications. The 2716 is also the first EPROM with a static standby mode which reduces the power dissipation without increasing access time. The maximum active power dissipation is 525 mW while the maximum standby power dissipation is only 132 mW, a 75% savings.

The 2716 has the simplest and fastest method yet devised for programming EPROMs - single pulse TTL level programming. No neeo for high voltage pulsing because all programming controls are handled by TTL signals. Program any location at any time-either individuallY, sequentially or at random, with the 2716'ssingle address location programming. Total programming time for all 16,384 bits is only 100 seconds.
