SC28L92 Philips Semiconductors, SC28L92 Datasheet - Page 11

• Manufacturer Part Number: SC28L92
• Description: 3.3V-5.0V Dual Universal Asynchronous Receiver/Transmitter DUART
• Manufacturer: Philips Semiconductors

1. Parameters are valid over specified temperature and voltage range.
2. All voltage measurements are referenced to ground (GND). For testing, all inputs swing between 0.4V and 3.0V 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. Input port pins have active pull-up transistors that will source a typical 2 A from V
6. All outputs are disconnected. Inputs are switching between CMOS levels of V
