AC Waveforms for Read Operation (1)
AT27C010/L
Notes: 1. Timing measurement reference level is 1.5V for -45
and -55 devices. Input AC drive levels are VIL =
0.0V and VIH = 3.0V. Timing measurement refer-
ence levels for all other speed grades are VOL =
0.8V and VOH = 2.0V. Input AC drive levels are VIL
= 0.45V and VIH = 2.4V.
2. OE may be delayed up to tCE - tOE after the falling
edge of CE without impact on tCE.
3. OE may be delayed up to tACC - tOE after the address is valid
without impact on tACC.
4. This parameter is only sampled and is not 100% tested.
5. Output float is defined as the point when data is no longer
driven.
Input Test Waveforms and Measurement Levels
For -45 and -55 devices
only:
Output Test Load
For -70, -90, -12, -15,
and -20 devices:
tR, tF < 5 ns (10% to 90%)
tR, tF < 20 ns (10% to 90%)
Note: CL = 100 pF including
jig capacitance, except for the
-45 and -55 devices, where
CL= 30 pF.
