Programming Waveforms

(1)

Notes:

1. The Input Timing Reference is 0.8V for V

IL

and 2.0V for V

IH

.

2. t

OE

and t

DFP

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

3. When programming the AT27LV020A a 0.1 µF capacitor is required across V

PP

and ground to suppress spurious voltage

transients.
