NOTE:
1. The voltage specifications are in terms of absolute values.
2. Specification is for one TX output pin to be shorted at a time. Should all three driver outputs be shorted simultaneously, device power dis-
sipation limits will be exceeded.
3. This condition could exceed package limitations.
SWITCHING CHARACTERISTICS
Typical values are at TA = 0 to 70°C; VCC = +5V +5%, unless otherwise specified. (See Figures 2 and 3)
