DS7831 DS8831 DS7832 DS8832
Dual TRI-STATE Line Driver
General Description
Through simple logic control the DS7831 DS8831
DS7832 DS8832 can be used as either a quad single-end-
ed line driver or a dual differential line driver They are spe-
cifically designed for party line (bus-organized) systems
The DS7832 DS8832 does not have the V_CC clamp diodes
found on the DS7831 DS8831
The DS7831 and DS7832 are specified for operation over
the b55 C to a125 C military temperature range The
DS8831 and DS8832 are specified for operation over the
0 C to a70 C temperature range
Features
Y _{Series 54 74 compatible}
Y _{17 ns propagation delay}
Y _{Very low output impedance high drive capability}
Y _{40 mA sink and source currents}
Y _{Gating control to allow either single-ended or differen-}
tial operation
Y _{High impedance output state which allows many out-}
puts to be connected to a common bus line
