AC Characteristics
Inputs are driven to 2.4 V for a logical "1" and to 0.4 V for a logical "0". Timing
measurements are made at 2.0 V for a logical "1" and 0.8 V for a logical "0". The AC
testing input/output wave forms are shown in Figure 103 below.

Microprocessor Interface Timing in Parallel Mode
The microprocessor interface timing in the parallel mode has been accelerated. This
allows using the IEC-Q in applications which demand high data transmission rates, e.g.
PCM-4, 8, or in applications with high speed microcontroller.
