53S440

The 53S440 is designed as 1024x4 bipolar PROMs featuring low input current PNP inputs, full schottky clamping with open collector or three-state outputs. The titanium-tungsten fuses store a logical low and are programmed to the high-state.

53S440 has five features. (1)35ns maximum access times. (2)Reliable tltanlum-tungsten fuses (TIW) guarantee greater than 98% programming yields. (3)Low voltage generic programming. (4)PNP input for low input current. (5)Open collector or three-state outputs. Those are all the main features.

Some absolute maximum ratings of 53S440 have been concluded into several points as follow. (1)Its supply voltage would be from -0.5V to 7V for operating and 12V for programming. (2)Its input voltage would be from -1.5V to 7V for operating and 7V for programming. (3)Its input current would be from -30mA to 5mA for operating. (4)53S440's off-state output voltage would be from -0.5V to 5.5V for operating and 12V for programming. (5)Its storage temperature range would be from -65°C to 150°C. 53S440 should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about 53S440 are concluded as follow. (1)Its low level input voltage would be max 0.8V. (2)Its high level input voltage would be min 2V. (3)53S440's input clamp voltage would be max -1.5V. (4)Its low level input current would be max -0.25mA. (5)Its high level input current would be max 40uA. (6)53S440's low level output voltage would be 0.45V for com and would be max 0.5V for mil. (7)Its high level output voltage would be min 2.4V. (8)Its off-state output current would be max -40uA at Vo=0.4V and would be max 40uA at Vo=2.4V. (9)Its output short-circuit current would be min -20mA and max -90mA. And so on.
