OUTPUTS

2.0 V

0.8 V

Note:

AC testing inputs are driven at 3.5 V for a logic “ 1” and 0.45 V for a logic

“ 0” . Timing measurements are made at 2.0 V for a logic “ 1” and 0.8 V for

a logic “ 0”.

VOH – 0.15 V

VOL + 0.15 V

Note:

For timing purposes, a port pin is no longer floating when a 150 mV change from load

voltage occurs and begins to float when a 150 mV change from the loading VOH/VOL

level occurs with IOL/IOH ≤ 15 mA.

(68-Lead PLCC)

36.5°C/W

10°C/W

NOTES:

1. θJA = Thermal resistance between junction and the surrounding environment (ambient). Measurements are

taken 1 ft. away from case in air flow environment.

θJC = Thermal resistance between junction and package surface (case).

2. All values of θJA and θJC may fluctuate depending on the environment (with or without airflow, and how

much airflow) and device power dissipation at temperature of operation. Typical variations are ±2°C/W.

3. Values listed are at a maximum power dissipation of 0.50 W.
