DESCRIPTION

· The MAX7461 is a single-channel loss-of-sync alarm (LOS) designed for composite video sync detection in NTSC, PAL, and SECAM SDTV systems.
· It features advanced detection circuitry to prevent false alarms caused by noise.
· The device accepts AC-coupled composite (CVBS), luma (Y), or any other video signal with sync and outputs a logic-level signal.
· The open-drain LOS output is low when no sync is detected and high impedance when sync is detected.
· It operates from a single +5V supply and is available in a 5-pin SOT23 package.
· Specified for operation over the -40°C to +85°C temperature range.

FEATURES

· Accepts CVBS, Y, or any other video signal with sync.
· Provides a loss-of-sync alarm output.
· Ensures robust performance in noisy environments.
· Supports Wire-OR alarm output.
· Compatible with NTSC, PAL, and SECAM standards.
· Compact 5-pin SOT23 package.

APPLICATIONS

· Security Systems.
· Consumer Electronics.
