FAST CMOS 16-BIT REGISTERED TRANSCEIVER
INDUSTRIAL TEMPERATURE RANGE
NOTES:
1. See test circuit and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. This limit is guaranteed but not tested.
4. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
