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

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.
