NOTES:

6. Maximum output swing is clamped nominally at

±6 V to enable the higher data rates associated with this device and to reduce EMI

emissions. The driver outputs may slightly exceed the maximum output voltage over the full VCC and temperature ranges.

7. Not more than one output should be shorted at one time.
