ELECTRICAL CHARACTERISTICS (Note 2)
The l denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing is done at VCC = 3V, V+ = 8V, V– = –8V, and
VON/OFF = 3V.
Note 3: Supply current is measured with all driver inputs tied high.
Note 4: Supply current measurements in SHUTDOWN are performed with
VON/OFF = 0.1V, V+ = 0V, V– = 0V.
Note 5: For driver delay measurements, RL = 3k and CL = 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (tPHL = 1.4V to 0V and tPLH = 1.4V to 0V).
Note 6: Receiver RXA (Pins 10 and 15, S Package) remains functioning in
SHUTDOWN.
Note 7: For receiver delay measurements, CL = 51pF. Trigger points are set
between the receiver’s input logic threshold and the output transition to
standard TTL/CMOS logic threshold (tLH = 1.3V to 2.4V and tHL = 1.7V to
0.8V).
