• Manufacturer Part Number: 74F521
• Description: 8-bit identity comparator
• Manufacturer: Philips

1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
3. Not more than one output should be shorted at a time. For testing I

of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
