• Manufacturer Part Number: scn2651
• Description: Programmable Communications Interface Pci
• Manufacturer: NXP Semiconductors

1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
2. For operating at elevated temperatures, the device must be derated based on +150 C maximum junction temperature.
3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effect of excessive static
4. Parameters are valid over operating temperature range unless otherwise specified. See ordering code table for applicable temperature
