AT27C040

14. Programming Waveforms(1)

Notes:

1. The Input Timing Reference is 0.8V for VIL and 2.0V for VIH.

2. t

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

3. When programming the AT27C040 a 0.1 µF capacitor is required across VPP and ground to suppress spurious voltage

transients.
