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 = –12mA
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
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
NOTES:
1. All typical values are at VCC = 3.3V and Tamb = 25°C.
