• Manufacturer Part Number: IMP8980DC
• Description: PCM Digital Switch
• Manufacturer: IMP [IMP, Inc]

† Timing is over recommended temperature & power supply voltages.
‡ Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
* High Impedance is measured by pulling to the appropriate rail with R
