Note 3. Measured at the bus side of the transformer, including the contribution from the transformer.
Note 4. Vcc= 5 Volts ±0.1 V, for all measurements unless otherwise specified.
Note 5. Specifications apply over the case temperature range of -55°C to +125°C unless otherwise specfied.
Note 6. All typical values are measured at +25°C
Note 7. A 1uf, 10 Volt capacitor is required on the TX/RX terminal for each transceiver as shown in Figure 5. A Sprague
194D type (.05" W x .10" L x .05" H ) is suggested.
