NOTES:

1. Industrial temperature range product for 15ns and 25ns speed grades are available

as a standard device.

2. Industrial temperature range product for 25ns speed grade only is available as a standard

device. All other speed grades are available by special order.

3. Military temperature range product for the 40ns is only available for 7203.

4. Commercial temperature range product for the 12ns not available.

5. Commercial temperature range product for the 12ns, 15ns and 50ns not available.

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.
