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.
I_CC is specified at 15 mA maximum, making the device ideal
for battery and power conscious applications. 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.
