Notes:
A. C
B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
C. All input impulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Z
D. The outputs are measured one at a time with one transition per measurement.
Power- Up Considerations
To avoid excessive supply current, bus contention or oscillation during power-up, the following guidelines should be followed:
1. Connect ground first before any supply voltage is applied.
2. Power up V
3. Ramp OE ahead of or with V
4. Ramp DIR with V
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
