Notes:

1. The internal Write time is defined by the overlap of

CE = LOW, UB and/or LB = LOW, and WE = LOW. All signals must be

referenced to the rising or falling edge of the signal that terminates the Write.

2. Tested with OE HIGH for a minimum of 4 ns before

WE = LOW to place the I/O in a HIGH-Z state.

3. WE may be held LOW across many address cycles and the

LB, UB pins can be used to control the Write function.
