The Input Timing Reference is 0.8V for V
IL
and 2.0V for V
IH
.
t
OE
and t
DFP
are characteristics of the device but must be accommodated by the programmer.
When programming the AT27C1024 a 0.1
µF
capacitor is reqired across V
PP
and ground to suppress sputious voltage tran-
sients.
DC Programming Characteristics
TA = 25 ± 5×C, VCC = 6.5 ± 0.25V, VPP = 13.0 ± 0.25V
