Notes:
This Figure shows the operation areas allowed for DC output characteristics of active negate
driver if negated. This Figure does not show the AC output characteristics. The AC output
characteristics may vary depending on the other requirements including the slew rate
specifications. The device load needs to be changed to measure the actual device DC
characteristics. Therefore, the test circuit of Figure 1.54 cannot be used for this measurement.

All single-ended type drivers shall keep the high-impedance state between the power-on and
power-off cycles.
The SCSI device shall satisfy the following specifications if the load capacitor (C
pF +/-5% and if the unbalanced test circuit of Figure 1.54 is used for measurement.
1) t (Rise rate) = 520 mV per ns at Max voltage (0.7 to 2.3 VDC)
rise
2) t (Fall rate) = 520 mV per ns at Max voltage (2.3 to 0.7 VDC)
fall
The timing characteristics of all other signal output shall be measured using the test circuit of
Figure 1.54 when the load capacitance (C
