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
CCA
, which is the control side of the device.
3. Ramp OE ahead of or with V
CCA
to help prevent bus contention
4. Ramp DIR with V
CCA
if DIR HIGH is needed (A bus to B bus). Otherwise keep DIR LOW.
Note:
8. Skew between any two outputs of the same device, switching in the same direction. Parameter guaranteed by design.
