4.75 to 5.5 Volts
Notes: 1. VCC = 5 Volts ±0.1 V, TC = -55°C to +125°C, unless otherwise specified.
2. Power ON/OFF, measured from 75KHz to 1MHz at Point A-A’. See Figure 5.
3. All typical values are measured at +25°C.
4. At point A-A’ on Figure 5, 2.5 µS after midpoint crossing of the parity bit of the last word of a 660 µS message.
5. Output Voltage Delta (VO∆) = VO(IDEAL) - VO(MEASURED), where VO(IDEAL) = Slope x VCONT and
Slope = ∆VO ÷ ∆VCONT, See Figure 3.
