The DIP footprint is socket-friendly: on a customer site with a basic extraction tool, this receiver swaps in minutes without a hot-air station or reflow profile. Orientation is obvious from the pin-1 notch, so a field swap is low-risk even without a schematic in hand.","metaTitle":"SN55189AJ Quad Line Receiver, Active, Bulk","metaDescription":"SN55189AJ quad line receiver from Texas Instruments.
