SC28L91 Philips Semiconductors, SC28L91 Datasheet - Page 11

• Manufacturer Part Number: SC28L91
• Description: 3.3V-5.0V Universal Asynchronous Receiver/Transmitter (UART)
• 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 0.4 V and 3.0 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. 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
