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.
CAPACITANCE(1) (TA=+25°C,f=1.0MHz)
NOTES:
1. This parameter is sampled and not 100% tested.
2. With output deselected.
