V DD = 3 to 4.5 V, f clk > 1.78 MHz: t h = 4350 – (7500/f clk )
V DD = 4.5 to 5.5 V, f clk > 2.34 MHz: t h = 3300 – (7500/f clk )
1. This restriction does NOT apply for f clk rates less than those listed above. For “slow” f clk rates, use the t h limits in the above table.
2. This restriction does NOT apply for an access involving more than 8 Clocks. For > 8 Clocks, use the t h limits in the above table.
