sense: if V
is inhibited. (b) V
reached the V
ically time out 10 ms (typical) before programming. (c)
Program inhibit: holding any one of OE low, CE high or
WE high inhibits program cycles. (d) Noise filter: pulses of
less than 15 ns (typical) on the WE or CE inputs will not
initiate a program cycle.

power supply, the address inputs and control inputs (OE,
CE, and WE) may be driven from 0 to 5.5V without ad-

This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
