DC ELECTRICAL CHARACTERISTICS

(Commercial: VCC = 5V ± 10%, TA = 0

°C to +70°C; Industrial: VCC = 5V ± 10%, TA = –40°C to +85°C; Military: VCC = 5V ± 10%, TA = –55°C to +125°C)

6. Measurements with 0.4

≤ VIN ≤ VCC.

7. R

≥ VIH, 0.4 ≤ VOUT ≤ VCC.

8. Tested with outputs open (IOUT = 0).

9. R and W toggle at 20 MHz and data inputs switch at 10 MHz.

10. ICC measurements are made with outputs open.

11. All Inputs = VCC - 0.2V or GND + 0.2V, except R and W, which toggle at 20MHz.

12. All Inputs = VCC - 0.2V or GND + 0.2V, except R and W = VCC -0.2V.
