DS14C202 Low Power 5V Powered EIA/TIA-232 Dual Driver/Receiver

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 signal le.
