Product details

HDMI interface protection and conditioning in a 38-TSSOP

It operates from a 5V to 5.5V supply rail, making it a drop-in fit for systems that already carry a 5V bus — typical in desktop PCs, CAD/CAM workstations, point-of-sale terminals, and audio/video equipment where HDMI port integrity matters.

Supply rail and power budget

If your system runs a 3.3V-only HDMI source, this part needs a separate 5V regulator or a boost converter. The 0.5V headroom above 5V is slim; a 5V rail that droops below 5V under load still keeps the IC happy, but anything above 5.5V needs a clamp or a different part.

ROHS3 compliant.
