Maximum Ratings[2]
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:
Maximum Input Voltage Relative to VSS:............. VSS – 0.3V
Maximum Input Voltage Relative to VDD:............. VDD + 0.3V
Storage Temperature: ................................–65°C to + 150°C
Operating Temperature:................................–40°C to +85°C
Maximum ESD protection ............................................... 2KV
Maximum Power Supply: ................................................5.5V
Maximum Input Current:...................................................±20mA
VSS < (Vin or Vout) < VDD
Unused inputs must always be tied to an appropriate logic volt-
age level (either VSS or VDD).
DC Parameters: VDDC = 3.3V ±5%, VDD = 3.3V ±5%, TA = –40°C to +85°C

Notes:
2. The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
3. Inputs have pull-up/pull-down resistors that effect input current.
4. The VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when the “High” input is within the VCMR
range and the input lies within the VPP specification.
5. Driving series or parallel terminated 50Ω (or 50Ω to VDD/2) transmission lines.
