NOTES:

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

2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND

3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V ± 0.3V a

transition time of 100µsec is permitted. This parameter is valid for Tamb = 25°C only.

4. Unused pins at VCC or GND.

5. ICCZ is measured with outputs pulled to VCC or GND.

6. This is the bus hold overdrive current required to force the input to the opposite logic state.

AC CHARACTERISTICS

GND = 0V; tR = tF = 2.5ns; CL = 50pF; RL = 500Ω; Tamb = –40°C to +85°C.
