AC Electrical Characteristics
(Over Recommended Operating Free-Air Temperature Range unless otherwise noted, See Figure 1 and 2)
Notes:
1. Skew between any two outputs of the same device, switching in the same direction. Parameter guaranteed by design.
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. Then Power up V
3. Ramp OE ahead of or with V
4. Ramp DIR with V
