The supply range of 5 V to 15 V covers the legacy ±12 V RS232 bus voltages common in industrial and telecom gear, and the 14-SOIC package keeps the board footprint small for a four-channel part. ## Supply range and temperature — where this driver fits It belongs in office equipment, test instruments, and indoor industrial controllers — not in an engine bay or an outdoor base station. The 5 V to 15 V supply gives you flexibility: run it from a single 5 V rail if the RS232 output swing is acceptable, or from a 12 V rail for full ±12 V compliance. No external charge pump capacitors are needed because the part uses the supply directly, unlike some newer RS232 transceivers that generate the negative rail internally.","metaTitle":"Texas Instruments LT1030CDRE4 Quad RS232 Line Driver","metaDescription":"Texas Instruments LT1030CDRE4 is a quad RS232 line driver in 14-SOIC, 5V to 15V supply, 0°C to 70°C.
