Absolute Maximum Ratings

Notes:
1. “Absolute maximum ratings” are those beyond which the safety of the device cannot be guaranteed. They are not meant to
imply that the device should be operated at these limits. If the device is subjected to the limits in the absolute maximum ratings
for extended periods, its reliability may be impaired. The tables of Electrical Characteristics provide conditions for actual
device operation.

Negative supply for the RC7315 output stage

as possible and then immediately connected to V
Analog program input that sets the output high level (V

OH
is nominally unity gain.
Differential digital inputs
. The output will toggle between the two levels dictated by V
and V
L
as the differential signal is switched. Although these inputs are normally driven
by ECL signals, they have a wide enough common mode range that any one of the
inputs may be driven by a TTL or CMOS signal provided that the other input is tied to
the appropriate threshold voltage.
Analog program input that sets the output low level (V
from V
L
to V
OL
is nominally unity gain.
Driver output on RC7315
. The output impedance is 8
back terminated in the characteristic impedance of the transmission line it drives. For a
50
W
line, a 40
W
±
1% resistor should be placed externally as close to the output pin as
possible to minimize reflections and ringing. The resistor should also be able to
dissipate 0.8
W
to sustain the short circuit current of the output.
