Notes: * VCC = 5 V, Ta = 25°C

** ICC is measured with all outputs open and all inputs at 4.5 V.

(Ta = –20 to +75 °C)

Condition

VCC = 4.75 V, VIH = 2 V, VIL = 0.8 V,

IOH = –400 µA

IOL = 4 mA VCC = 4.75 V, VIH = 2 V,

IOL = 8 mA VIL = 0.8 V

VCC = 5.25 V, VI = 2.7 V

VCC = 5.25 V, VI = 0.4 V

VCC = 5.25 V, VI = 7 V
