DS7831 DS8831 DS7832 DS8832 Dual TRI-STATE Line Driver
February 1996
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
b
55 C to
a
125 C military temperature range The
DS8831 and DS8832 are specified for operation over the
0 C to
a
70 C temperature range
