Notes:

The input timing reference level is 0.8V for VIL and 2.0V for VIH.

tDF and tOE are characteristics of the device but must be accommodated by the programmer.

VCC = 6.5V

±0.25V, VPP = VH = 13.0V ±0.5V for express programming algorithm.

Read Mode

(See Timing Diagrams and AC Characteristics)

Read Mode is accessed when

a)

the CE pin is low to power up (enable) the chip

b)

the OE/VPP pin is low to gate the data to the

output pins

For Read operations, if the addresses are stable, the

address access time (tACC) is equal to the delay from

CE to output (tCE). Data is transferred to the output

after a delay (tOE) from the falling edge of OE/VPP.
