Note 1: C1–C4 = 0.1µF, tested at +3.3V ±10%. C1 = 0.047µF, C2–C4 = 0.33µF, tested at +5.0V ±10%.
Note 2: All supply current measurements are made under no-load condition on all outputs, and all input voltages are at V
CC
or GND.
Note 3: For a compliant IrDA input signal where the data rate is within the supported data rate for the IR receive mode: rise/fall
times are less than 600ns and pulse widths are between 1.41µs and 3/16 of the baud rate.
