Electrical Characteristics

Transceiver

Tested @ Tamb = 25 °C, VCC1 = VCC2 = 2.7 V to 5.5 V unless otherwise noted.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

*) Standard illuminant A

**) To provide an improved immunity with increasing V

logic the typical threshold level is increasing with Vlogic and set to 0.5 x Vlogic. It is

recommended to use the specified min/max values to avoid increased operating current.
