Note 2: Vcc = 5 Volts ±0.1 V, bypassed by 2.2 µF (Tantalum recommended) Capacitor minimum. All measurements &

specifications apply over the temperature range of -55°C to +125°C (case temperature) unless otherwise

specified.

Note 3: When measured at point A-A’ with ± 10 Volt peak, line to ground, DC to 2MHz

Note 4: Typical power is measured with Vbus at point A-A’ = 7.5 VP-P
