Product Summary

The AM27S191DMB is a Schottky TTL programmable Read-Only Memory. The AM27S191DMB has three-state outputs which is compatible with low-power schottky bus standards capable of satisfying the requirements of a variety of micro programmable controls, mapping functions, code conversion, or logic replacement. Easy word-depth expansion is facilitated by both active Low and active High output enables. The AM27S191DMB is also available in 300-mil, lateral center DIP.


AM27S19/BEA absolute maximum ratings: (1)Storage Temperature: -65℃ to +150℃; (2)Ambient Temperature with power Applied: -55℃ to +125℃; (3)Supply voltage: -0.5V to +7.0V; (4)DC voltage applied to outputs (except during programming): -0.5V to +VCC Max.; (5)DC voltage applied to outputs (during programming): 21V; (6)Output Current into Outputs During Programming (Max. Duration of one sec): 250mA; (7)DC Input Voltage: -0.5V to +5.5V; (8)DC Input Current: -30mA to +5mA.


AM27S19/BEA features: (1)Fast access time allows high system speed; (2)50% power saving on deselected parts-enhances reliability through total system heat reduction; (3)Plug in replacement for industry standard produce- no board changes required; (4)Voltage and temperature compensated providing extremely flat AC performance over military range; (5)Rapid recovery from power-down state provides minimum delay.
