DESCRIPTION
The DS276 Line–Powered RS–232 Transceiver Chip is
a CMOS device that provides a low–cost, very low–
power interface to RS–232 serial ports. The receiver
input translates RS–232 signal levels to common
CMOS/TTL levels. The transmitter can be used with
independently supplied positive and negative supplies,
but in most cases will be used with the positive supply
sharing the logic supply and the negative supply stolen
from the receive RS–232 signal when that signal is in a
negative state (marking). By using an external reservoir
capacitor and Schottky diode (see Figure 4) this nega-
tive supply can be maintained even during full–duplex
operation. Since most serial communication ports
remain in a negative state statically, using the receive
signal for negative power greatly reduces the DS276’s
static power consumption. This feature is especially
important for battery–powered systems such as laptop
computers, remote sensors, and portable medical
instruments. During an actual communication session,
the DS276’s transmitter will use system power (3–12
volts) for positive transitions while still employing the
receive signal for negative transitions.
