Overview
The EL4581CN is a video sync separator integrated circuit manufactured by Renesas Electronics Corporation. It operates on a single 5V supply with a typical current consumption of 1.5 mA. The device extracts timing information from standard negative-going video sync signals found in NTSC, PAL, and SECAM broadcast systems. It features a 50% slicer, sample-and-hold function, and filter capabilities. The component is housed in an 8-pin PDIP package and is rated for operation between -40°C and +85°C. This part is currently obsolete.

Procurement Notes
Verify component authenticity through authorized channels as the EL4581CN is officially obsolete. Confirm package integrity and pin alignment against original specifications. Check for moisture sensitivity damage if storage conditions were not strictly controlled. Ensure replacement strategies account for the discontinued status of this specific Renesas part number.
Selection Notes
Select this component only when legacy compatibility with NTSC, PAL, or SECAM sync separation is required. Verify that the 8-pin DIP package fits the existing board layout. Confirm that the 5V supply voltage aligns with the system design. Evaluate alternative solutions if new designs do not require this specific obsolete interface.
