Runs from a 2.25V to 3.6V supply rail — covers both 2.5V and 3.3V logic domains without an extra regulator.
The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a low-profile footprint that suits dense PCB layouts where height is constrained.
Listed as Active by Microchip Technology.
Yes, the function is Enable/Disable. When disabled, the supply current drops to 22 mA max, useful for power-saving modes.
CMOS output — it drives standard digital logic inputs directly without external level translation.
