Note 2: Does not include external feedback network resistance.

Note 3: Applies to all digital input pins (EN, LE, and A0).

Note 4: Specified with feedback network chosen for optimal AC performance. See Tables 1 and 2 for recommended component

values.

Note 5: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0IRE to 100IRE). IRE is a unit of

video-signal amplitude developed by the International Radio Engineers. 140IRE = 1.0V.

Note 6: See timing diagram (Figure 5).

Note 7: Channel-switching time specified for switching between the two input channels; does not include signal rise/fall times for

switching between channels with different input voltages.

Note 8: Guaranteed by design; not production tested.

Note 9: Output enable/disable delay times do not include amplifier output slewing times.

Note 10: Switching transient measured while switching between two grounded channels.
