They have 8,192 bits organizedas 1024 words of 8-bit length. The devices arefabricated using N-channel silicon-gate technology forhigh speed and simple interface with MOS and bipolarcircuits. All inputs (including program data inputs) canbe driven by Series 54/74 TTL circuits without the useof external pull-up resistors. Each output can drive oneSeries 54/74 or 54LS/74LS TTL circuit without externalresistors. The '27L08 guarantees 200 mV dcnoise immunity in the high state and 250 mV in thelow state. The data outputs for the '2708-35,'2708-45, and 'Z7L08-45 are three-state for OR-tyingmUltiple devices on a common bus.A5A4NCA3A2A1AO0102AO-A7NCPGM01-08S(PE)VBBVCCVDDVSSTMS2708 ...
