SCC2692 Philips, SCC2692 Datasheet - Page 6

• Manufacturer Part Number: SCC2692
• Description: Dual asynchronous receiver/transmitter DUART
• Manufacturer: Philips

1. Parameters are valid over specified temperature range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4V and 2.4V with a transition time of 5ns
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
6. T
7. T
8. See UART application note for 5 A.
