Low-Power Audio/Video Switch with Audio
Volume Control for Dual SCART Connectors
ELECTRICAL CHARACTERISTICS (continued)
(V12 = 12V, VVID = VAUD = 3.3V, VGNDVID = VEP = 0V, no load, TA = 0°C to +70°C, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 2)

VCLP
Sync-tip clamp
Sync-tip clamp; percentage reduction in
sync pulse (0.3VP-P); guaranteed by input
clamping current measurement, TA = +25°C
Sync-tip clamp, VIN = 0.3V, TA = +25°C
Input sync-tip circuit must be stable even if
the source resistance is as high as 300Ω
