Preliminary Information
MH88422
2-21
AC Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
Typical figures are at 25
°
C with nominal +5V and are for design aid only.
Note 1: All of the above test conditions use a test source impedance which matches the device’s impedance.
