Features, Applications

Wide Operating Voltage Range 6 V High-Current Outputs Drive To 10 LSTTL Loads Low Power Consumption, 80-A Max ICC

Typical tpd ns 4-mA Output Drive 5 V Low Input Current 1 A Max Compare Two 8-Bit Words

These identity comparators perform comparisons of two 8-bit binary or BCD words. An output-enable (OE) input may be used to force the output to the high level. ORDERING INFORMATION

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7.
