74AC11520

The 74AC11520 is designed as 8-bit identity comparator which performs comparisons on two 8-bit binary or BCD words. Features include 20kohms pullup termination resistors on the Q inputs for analog or switch data and a P=Q totem-pole output.

The six features of the 74AC11520. (1)Compares two 8-bit words. (2)Center-pin Vcc and GND configurations minimize high-speed switching noise. (3)EPIC (enhanced-performance implanted CMOS) 1um process. (4)500mA typical latch-up immunity at 125°C. (5)Equivalent of 20kohms pullup resistor on Q inputs. (6)Package options include plastic small-outline packages (DW) and standard plastic 300mil DIPs (N). Those are all the main features.

Some absolute maximum ratings of the 74AC11520 have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 7V. (2)Its input voltage range would be from -0.5V to Vcc+0.5V. (3)Its output voltage range would be from -0.5V to Vcc+0.5V. (4)Its input clamp current would be +/-20mA. (5)Its output clamp current would be +/-50mA. (6)Its continuous output current would be +/-50mA. (7)Its continuous current through Vcc or GND would be +/-100mA. (8)Its storage temperature range would be from -65°C to 150°C. (9)Its maximum power dissipation at Ta=55°C would be 1.6W for DW package and would be 1.3W for N package. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

And some electrical characteristics of the 74AC11520 are concluded as follow. (1)Its Voh would be min 2.9V. (2)Its Vol would be max 0.1V. (3)Its Ii would be max +/-0.1uA. (4)Its Icc would be max 8uA. (5)Its Ci would be typ 3.5pF. (6)Its power dissipation capacitance would be typ 42pF. (7)Its tPLH would be min 1.5ns and max 18.6ns from input P or Q. (8)Its tPHL would bemin 1.5ns and max 16.3ns from input P or Q. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
