SC28L91 Philips Semiconductors, SC28L91 Datasheet - Page 10

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