NOTES:

7. Minimum RS-232 driver output voltages are not attained with

±5-V supplies. With VDD less than VCC + 2 V, the supply currents may

increase. For RS-232 compliant output swings and minimum power consumption, VDD ≥ VCC + 2 V.

8. Maximum output swing is nominally clamped 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.

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