Maximum Ratings[3]
Input Voltage Relative to VSS:.............................. VSS – 0.3V
Input Voltage Relative to VDD: ............................. VDD + 0.3V

Operating Temperature: ................................ –40°C to +85°C
Maximum Power Supply: ................................................5.5V
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric field; however,
precautions should be taken to avoid application of any volt-
age higher than the maximum rated voltages to this circuit. For
proper operation, Vin and Vout should be constrained to the
range:
VSS < (Vin or Vout) < VDD
Unused inputs must always be tied to an appropriate logic volt-
age level (either VSS or VDD).
Notes:
3.
Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply srquencing is NOT required.
4.
The VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when “High” input is within the VCMR range
and the input lies within the VPP specification.
5.
Inputs have pull-up/pull-down resistors that effect input current.
6.
Driving series or parallel terminated 50
Ω (or 50Ω to V
DD/2) transmission lines.
DC Parameters: VDD = VDDC = 3.3V ±10%, TA = –40°C to +85°C
