that the devices should be operated at these limits. The table of Electrical Characteristics specifies conditions of device operation.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Only one driver output shorted at a time.

(1) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced 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 6V is a maximum, the
typical value (6.8V) is more negative.

(3) Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced 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 6V is a maximum, the
typical value (6.8V) is more negative.
(4) If receiver inputs are unconnected, receiver output is a logic high.
