DS14C202
Low Power +5V Powered EIA/TIA-232 Dual
Driver/Receiver
General Description
The DS14C202 is a low power dual driver/receiver featuring
an onboard DC to DC converter. This eliminates the need for
±12V power supplies and requires only a +5V power supply.
Only four 0.1 µF capacitors are needed for the DC to DC
converter. The drivers maintain greater than ±5V output sig-
nal levels at data rates in excess of 128 kbits/sec when
loaded in accordance with the EIA/TIA-232-E specification.

device ideal
The drivers’
slew rate is set internally, eliminating the need for external
slew rate capacitors. The device is designed to interface
data terminal equipment (DTE) with data circuit-terminating
equipment (DCE). The driver inputs and receiver outputs are
TTL and CMOS compatible. DS14C202 driver outputs and
receiver inputs meet EIA/TIA-232-E and ITU-T V.28 stan-
dards. This device is an enhanced version of the DS14C232
that requires smaller external capacitors (0.1 µF) and sup-
ports higher data rates of up to 128 kbit/sec.
Features
n Uses only four small 0.1 µF capacitors for DC to DC
converter
