DS78C120 DS88C120 Dual CMOS Compatible
Differential Line Receiver
General Description
The DS78C120 and DS88C120 are high performance dual
differential CMOS compatible line receivers for both bal-
anced and unbalanced digital data transmission The inputs
are compatible with EIA Federal and MIL standards
Input specifications meet or exceed those of the popular
DS7820 DS8820 line receiver
The line receiver will discriminate a g200 mV input signal
over a common-mode range of g10V and a g300 mV sig-
nal over a range of g15V
Circuit features include hysteresis and response control for
applications where controlled rise and fall times and or high
frequency noise rejection are desirable Threshold offset
control is provided for fail-safe detection should the input
be open or short Each receiver includes a 180X terminating
resistor and the output gate contains a logic strobe for time
discrimination The DS78C120 is specified over a b55 C to
a125 C temperature range and the DS88C120 from 0 C to
a70 C
