NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. Typical values are at VDD = 2.5V, +25°C ambient.
3. For A[1:2] single-ended operation, A[1:2] is tied to a DC reference voltage.

NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. VDIF specifies the minimum input differential voltage (VTR - VCP) required for switching where VTR is the "true" input level and VCP is the "complement" input level. The DC differential
voltage must be maintained to guarantee retaining the existing HIGH or LOW input. The AC differential voltage must be achieved to guarantee switching to a new state.
3. VCM specifies the maximum allowable range of (VTR + VCP) /2.
4. Typical values are at VDD = 2.5V, +25°C ambient.
