RC7310
PRODUCT SPECIFICATION

Description (continued)
The supply rails may be raised by 2V to achieve an output
high level (V
OH
) of +1 0V, or towered by 2V to achieve an
output low level (V
OL
) of -5V. At all times there must be at
least a 2V margin between the positive supply and the maxi-
mum value of V
minimum value of V
OH
, and between the negative supply and the
OL
.
The RC7310 is implemented using Fairchild Semiconduc-
tor’s high performance precision Complementary Bipolar
Process (CBiP).

Pin Function Description
An optional 10,000 pF chip capacitor could be placed between CIM1 and CIM2 to
improve impedance matching across different voltage swings. With this capacitor,
output impedance stays more constant with changes in voltage swings. If not used,
leave pins CIM1 and CIM2 open.
Chip ground. These pins should be connected to the printed circuit board’s ground
plane at the pins.
On chip filter to improve output waveform (optional). This pin connection is optional
and should be left unconnected if not used. When used, the OF pin should be fed to
the termination node that is directly connected to the DUT.
Absolute slew rate control. By applying current at this pin, small changes in slew rate
can be programmed with an external DAC. This control pin affects both positive and
negative edge rates. If this slew rate control is not desired this pin should be left
open.
Slew rate control matching. By applying current at this pin, small changes in slew
rate can be programmed with an external DAC. This control pin adjusts the match
between positive and negative edges . If this slew rate control is not desired this pin
should be left open.
Active low output notifies thermal shutdown has occurred. In the event of a short-
circuit or other fault that causes the die temperature to rise between 115
160
°
C, the thermal shutdown will activate. If the fault persists, the device will toggle
back and forth between shutdown and normal operation at a frequency in the tens of
Hertz. TS is an open collector output capable of driving two standard TTL loads. The
TS pins of several drivers may be wired together and input to a latch to indicate an
alarm condition.
Pin used for factory testing the thermal characteristics of the device. The pin should
be left unconnected or tied to GND.
