Programming Waveforms (1)
Notes: 1. The Input Timing Reference is 0.8V for VIL and
2.0V for VIH.
2. tOE and tDFP are characteristics of the device but
must be accommodated by the programmer.
3. When programming the AT27C256R a 0.1 µF capacitor is
required across VPP and ground to suppress spurious voltage
transients.
