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
±
supply. I
device 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 exter-
nal 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.
