DC ELECTRICAL CHARACTERISTICS

Over recommended operating conditions voltages are referenced to GND (ground = 0V)

SYMBOL

PARAMETER

TEST CONDITIONS

VIH

HIGH level Input voltage

VCC = 1.2V

VCC = 2.7 to 3.6V

VIL

LOW level Input voltage

VCC = 1.2V

VCC = 2.7 to 3.6V

VCC = 2.7V; VI = VIH or VIL; IO = –12mA

VOH HIGH level output voltage

VCC = 3.0V; VI = VIH or VIL; IO = –100µA

VCC = 3.0V; VI = VIH or VIL; IO = –18mA

VCC = 3.0V; VI = VIH or VIL; IO = –24mA

VCC = 2.7V; VI = VIH or VIL; IO = 12mA

VOL LOW level output voltage

VCC = 3.0V; VI = VIH or VIL; IO = 100µA

VCC = 3.0V; VI = VIH or VIL; IO = 24mA

II

Input leakage current

VCC = 3.6V; VI = 5.5V or GND

IOZ

3-State output OFF-state current

VCC = 3.6V; VI = VIH or VIL; VO = 5.5V or GND

IOFF Power off leakage current

VCC = 0.0V; VI = 5.5V; VO = 5.5V

ICC

Quiescent supply current

VCC = 3.6V; VI = VCC or GND; IO = 0

∆ICC

Additional quiescent supply current per

input pin

VCC = 2.7V to 3.6V; VI = VCC –0.6V; IO = 0
