4 / 6 page Aeroflex Circuit Technology SCD4419D REV F 2/10/00 Plainview NY (516) 694-6700 4 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.
