DS14C232
Low Power +5V Powered TIA/EIA-232 Dual
Driver/Receiver
General Description
The DS14C232 is a low power dual driver/receiver featuring
an onboard DC to DC converter, eliminating the need for
±
12V power supplies. The device only requires a +5V power
supply. I
CC
is specified at 3.0 mA maximum, making the de-
vice ideal for battery and power conscious applications. The
drivers’ slew rate is set internally and the receivers feature
internal noise filtering, eliminating the need for external slew
rate and filter 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. DS14C232C driver outputs and
receiver inputs meet TIA/EIA-232-E (RS-232) and CCITT
V.28 standards.
