SC28L202 Philips Semiconductors, SC28L202 Datasheet - Page 65

• Manufacturer Part Number: SC28L202
• Description: Dual universal asynchronous receiver/transmitter DUART
• Manufacturer: Philips Semiconductors

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 3.0V with a transition time of 5 ns
3. Typical values are at +25 C, typical supply voltages, and typical processing parameters.
4. Test conditions for outputs: C L = 150 pF, except interrupt outputs. Test conditions for interrupt outputs: C L = 50 pF, R L = 2.7K ohm to V
5. Input port pins have active pull up transistors that will source a typical 2 A from Vcc when the input pins are at Vss. Input port pins at Vcc
6. All outputs are disconnected. Inputs are switching between CMOS levels of V
7. See UART application note for power down currents of 10 ua or less.
