It handles NTSC, PAL, and SECAM formats without external adjustment, making it a single-component solution for sync stripping in video processing chains. The part operates from a 5V to 12V supply, which gives flexibility to run off a common 5V logic rail or a higher analog supply without a separate regulator. The through-hole 8-DIP package (0.300\" row spacing) suits prototyping, repair work, and low-to-medium volume production where hand-assembly or socketing is preferred. ## Standalone operation — no external sync separator needed The LM1881N is a standalone sync separator. It takes a composite video input (1 Vpp typical) and outputs separate composite sync, vertical sync, and burst/back-porch gate signals. No external sync-separator chip or discrete transistor circuit is required. The only external components are a few coupling capacitors and pull-up resistors on the open-collector outputs. ## Through-hole 8-DIP — legacy footprint, easy to work with The 8-DIP (0.300\", 7.62mm) package is a standard through-hole footprint that fits into existing sockets or can be soldered directly into a PCB. The 8-PDIP supplier package code is the same physical part. For rework or prototyping, the DIP package is straightforward to remove and replace without hot-air equipment.","metaTitle":"LM1881N Sync Separator IC, NTSC/PAL/SECAM, 8-DIP","metaDescription":"LM1881N video sync separator IC from Texas Instruments.
