54AC11521

The 54AC11521 is designed as 8-bit identity comparator which performs comparisons on two 8-bit binary or BCD words. Also included is a P=Q totem-pole output.

54AC11521 has six features. (1)Compares two 8-bit words. (2)Flow-through architecture optimizes PCB layout. (3)Center-pin Vcc and GND configurations minimize high-speed switching noise. (4)EPIC (enhanced-performance implanted CMOS) 1um process. (5)500mA typical latch-up immunity at 125°C. (6)Package options include plastic small-outline packages, plastic shrink small-outline packages, ceramic chip carriers, and standard plastic and ceramic 300mil DIPs. Those are all the main features.

Some absolute maximum ratings of 54AC11521 have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 6V. (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. 54AC11521 should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

And some electrical characteristics of 54AC11521 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 4pF. (6)Its power dissipation capacitance would be typ 42pF. (7)Its tPLH would be min 1.5ns and max 16.6ns from input P or Q. (8)Its tPHL would bemin 1.5ns and max 14.1ns from input P or Q. (9)Its tPLH would be min 1.5ns and max 9.8ns from input G. (8)Its tPHL would be min 1.5ns and max 8.8ns from input G. And so on.
