Product details

The Texas Instruments SN75DP139RGZR is a specialized interface IC for desktop and notebook PC applications. The device comes in a 48-VQFN (7x7 mm) exposed-pad package, surface-mount only.

The 3V to 3.6V supply range ties this part to the common 3.3V rail found in most desktop and notebook motherboards. No extra regulator is needed if your board already runs a 3.3V plane. The I²C interface lets a system controller configure the device without dedicated GPIO lines — useful when you are already running a management bus for other peripherals.

The SN75DP139RGZR is listed as Active.
