• Manufacturer Part Number: scc2681
• Description: Dual Asynchronous Receiver/transmitter Duart
• 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 damaging effects of excessive static
4. Parameters are valid over specified temperature range. See Ordering information table for applicable operating temperature range and V
1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4 V and 2.4 V with a transition time of
3. Typical values are at +25 C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: C
5. All outputs are disconnected. Inputs are switching between CMOS levels of V
