NOTES:
1. For differential input mode, RxS is tied to GND.
2. Both differential input signals should not be driven to the same level simultaneously. The input will not change state until the inputs have crossed and the voltage range defi ned by VDIF
has been met or exceeded.
3. Differential mode only. VDIF specifi es the minimum input voltage (VTR - VCP) required for switching where VTR is the "true" input level and VCP is the "complement" input level. The AC
differential voltage must be achieved to guarantee switching to a new state.
4. For single-ended operation, A/VREF is tied to DC voltage (VREF). Refer to each input interface's DC specifi cation for the correct VREF range.
5. Voltage required to switch to a logic HIGH, single-ended operation only.
6. Voltage required to switch to a logic LOW, single-ended operation only.
