Either voltage limit or current datzsheet is sufficient to protect inputs. The multiple input enables allow parallel expansion to a 1-of decoder using just three F devices or a 1-of decoder using four F devices and one inverter. Current Applied to Output Note 2: Absolute maximum ratings are values beyond which the device. Devices also available in Tape and Reel.
