FEATURES…
The multi–channel RS-232 line drivers/receivers pro-
vides a variety of configurations to fit most communi-
cation needs, especially those applications where
±
12V is not available. The
SP230A
,
SP235A/B
,
SP236A/B, SP240A/B
, and
SP241A/B
feature a
shutdown mode which reduces device power dissipa-
tion to less than 5
μ
W. All feature low power CMOS
operation, which is particularly beneficial in battery-
powered systems. The
SP235A/B
use no external
components and are ideally suited where printed
circuit board space is limited.
All products in the Series include two charge pump
voltage converters which allow them to operate from
a single +5V supply. These converters convert the
+5V input power to the
±
10V needed to generate
the RS-232 output levels. An internal charge pump
converter produces the necessary –12V supply.
All drivers and receivers meet all EIA RS-232D
and CCITT V.28 specifications.
The Series are available for use over the commer-
cial, industrial and military temperature ranges.
They are packaged in plastic DIP and SOIC
packages. For product processed and screened to
MIL–M–38510 and MIL–STD–883C require-
ments, please consult the factory.
THEORY OF OPERATION
The
SP230A/B–241A/B
series devices are made up
of three basic circuit blocks – 1) transmitter, 2) receiver
and 3) charge pump. Each model within the series
incorporates variations of these circuits to achieve the
desired configuration and performance.
Driver/Transmitter
The drivers are inverting transmitters, which accept
TTL or CMOS inputs and output the RS-232 signals
with an inverted sense relative to the input logic levels.
Typically the RS-232 output voltage swing is
±
9V.
Even under worst-case loading conditions of 3k
and
2500pF, the output is guaranteed to be
±
5V, which is
consistent with the RS-232 standard specifications.
The transmitter outputs are protected against infi-
nite short-circuits to ground without degradation
in reliability.
The drivers of the
SP230A, SP235A/B, SP236A/B,
SP240A/B
and
SP241A/B
can be tri-stated by using
the SHUTDOWN function. In this “power-off” state,
the output impedance will remain greater than 300
Ohms, again satisfying the RS-232 specifications.
Should the input of the driver be left open, an internal
400k
pull–up resistor to V
forces the input high,
thus committing the output to a low state.
The slew rate of the transmitter output is internally
limited to a maximum of 30V/
μ
s in order to meet the
