NOTES
1All typicals are given for V

°C.
2Current into device pins is defined as positive. Current out-of-device pins is defined as negative. All voltages are referred to ground unless otherwise specified. For
current, minimum and maximum values are specified as an absolute value and the sign is used to indicate direction. For voltage logic levels, the more positive value is
designated as maximum. For example, if –6 V is a maximum, the typical value (–6.8 V) is more negative.
3Only one driver output shorted at a time.
4If receiver inputs are unconnected, receiver output is a logic high.
5Refer to typical curves. Driver output slew rate is measured from the +3.0 V to the –3.0 V level on the output waveform. Slew rate is determined by load capacitance.
Specifications subject to change without notice.
