Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS

(VCC = +4.5V to +5.5V, GND = 0, CIN = 0.1µF, RO = 500Ω, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA =

+25°C.)

Note 1: Minimum input sync height is the voltage above which LOS is guaranteed to be in high-impedance mode after the maximum

LOS time-constant time.

Note 2: LOS release time is the time that the video input must be continuously present before LOS goes high (inactive state).

Note 3: The LOS detect time is the time that the video input must be continuously absent before LOS goes low (active state).

Note 4: The MAX7461 LOS output is accurate with a power-supply noise level below VPSNI.
