general description
c Through simple logic control, the DM7831/
DM8831, DM7832/DM8832 can be used as either
a quad single-ended line driver or a dual differential
line driver. They are specifically designed for
party line (bus-organized) systems. The DM7832/
DM8832 does not have the Vee clamp diodes
found on the DM7831/DM8831.
The DM7831 & DM7832 are specified for opera-
tion over the -55°C to +125°C military tempera-
ture range. The DM8831 & DM8832 are specified
for operation over the O°C to +70°C temperature
range.
features
• Series 54174 compatible
• 17 ns propagation delay
• Very low output impedance-high dril,
capability
• 40 mA sink and source currents
• Gating control to allow either single-ended or
differential operation
• High impedance output state which allows
many outputs to be connected to a common
bus line.
mode of operation
To operate as a quad single-ended line driver apply
logical "O"s to the Output Disable pins (to keep
the outputs in the normal low impedance mode)
and apply logical "O'''s to both Differential/
Single·ended Mode Control inputs. All four
channels will then operate independently and no
signal inversion will occur between inputs and
outputs.
To operate as a dual differential line driver apply
logical "O"s to the Output Disable pins and apply
at least one logical "1" to the Differential/Single-
ended Mode Control inputs. The inputs to the A
channels should be connected together and the
inputs to the B channels should be connected to-
In this mode the signals applied to the resulting
inputs will pass non·inverted on the A2 and B2 out-
puts and inverted on the A, and B, outputs.
When operating in a bus-organized system with
outputs tied directly to outputs of other
