DC ELECTRICAL CHARACTERISTICS (continued)

(VCC - VEE = +2.25V to +3.8V, outputs loaded with 50

Ω ±1% to VCC - 2.0V. Typical values are at VCC - VEE = +3.3V, VIHD = VCC - 1V,

VILD = VCC - 1.5V, unless otherwise noted.) (Notes 1–5)

AC ELECTRICAL CHARACTERISTICS

(VCC - VEE = +2.25V to +3.8V, outputs loaded with 50

Ω ±1% to VCC - 2V, input frequency = 1.5GHz, input transition time = 125ps

(20% to 80%), VIHD = VEE + 1.2V to VCC, VILD = VEE to VCC - 0.15V, VIHD - VILD = 0.15V to the smaller of 3V or VCC - VEE. Typical

values are at VCC - VEE = 3.3V, VIHD = VCC - 1V, VILD = VCC - 1.5V, unless otherwise noted.) (Notes 8, 11)
