(1) This parameter is tested initially and after a design or process change that affects the parameter.

(2) tPUR and tPUW are the delays required from the time VCC is stable until the specified operation can be initiated.

(3) This parameter is tested initially and after a design or process change that affects the parameter.

(4) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V.
