AC ELECTRICAL CHARACTERISTICS VCC = 5V ±5%, VEE = –5V ±5% (Note 2)
The q denotes specifications which apply over the full operating
temperature range.
Note 1: The Absolute Maximum Ratings are those values beyond which
the life of a device may be impaired.
Note 2: All currents into device pins are positive; all currents out of device
pins are termed negative. All voltages are referenced to device ground
unless otherwise specified.
Note 3: Receiver enable to output valid high or low from shutdown is
typically 2
µs.
