TIMING CHARACTERISTICS
Detailed timing diagrams for the QE1M device are illustrated in Figures 5 through 17, with values of the timing
intervals tabulated below the waveform diagrams. The tristate condition of a signal waveform is shown as mid-
way between high and low. The timing parameters are measured at voltage levels of (V
nals or (V
both A and B bus signals, their symbols are combined in labeling the waveform (e.g., A/BADD for AADD and
BADD).
Notes:
1. TCIn is shown for TCLKI = 0, where data is clocked in on falling edges. Data is clocked in on rising edges
2. For NRZ operation, TNIn is not used for data input and may instead be used as the input for an external
