• Manufacturer Part Number: scn68681
• Description: Dual Asynchronous Receiver/transmitter Duart
• Manufacturer: NXP Semiconductors

1. Parameters are valid over specified temperature range. See Ordering information table for applicable operating temperature range and V
2. All voltage measurements are referenced to ground (GND). For testing, all inputs except X1/CLK swing between 0.4 V and 2.4 V with a
3. Typical values are at +25 C, typical supply voltages, and typical processing parameters.
