DC ELECTRICAL CHARACTERISTICS (Continued)

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

SYMBOL

TEST CONDITIONS

II

Input leakage current

VCC = 3.6V; VI = 5.5V or GND Not for I/O pins

IOZ

3-State output OFF-state current

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

Ioff

Power off leakage supply

VCC = 0.0V; VI or 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

NOTES:

1. All typical values are at VCC = 3.3V and Tamb = 25°C.

2. The specified overdrive current at the data input forces the data input to the opposite logic input state.

AC WAVEFORMS

VM = 1.5V at VCC w 2.7V; VM = 0.5 VCC at VCC t 2.7V.

VOL and VOH are the typical output voltage drop that occur with the

output load.

VX = VOL + 0.3V at VCC w 2.7V; VX = VOL + 0.1 VCC at VCC t 2.7V

VY = VOH –0.3V at VCC w 2.7V; VY = VOH – 0.1 VCC at VCC t 2.7V
