The following I/O read time delays were measured.
The measurements were taken at the 50% points under the following conditions.
• T = -40°C to 85°C, V = 5.0 V ±10%
• Internal clock to nonloaded CLK pin delay ≤ 1 ns @ 85°C/4.5 V
The following I/O write time delays were measured.
The measurements were taken at the 50% points under the same conditions that the I/O
read delays were measured.
