SUPPLY, 235KBPS,

MULTICHANNAEL RS-232 LINE

DRIVERS/RECEIVERS

DESCRIPTION

The UTC UT13243 consists of 3 drivers and 5 receivers. It meets

ElA/TIA-232 and V.28/V.24 specifications, it intended for notebook

computer applications. A high-efficiency, dual charge-pumps power

supply and a low-dropout transmitter combine to deliver true RS-232

performance from a single +3.0V ~ +5.5V power supply. A

guaranteed data rate of 120kbps provides compatibility with popular

software for communicating with PCs.

The UTC UT13243 achieves 1µA supply current in shutdown condition. When the UT13243 doesn’t detect a valid

signal level on its receiver inputs, the on-board power supply and drivers will shutdown, and when a valid level is

applied to any RS-232 receiver input, then the system turns on again. Therefore, the system saves power without

changes to the existing BIOS or operating system.

The UTC UT13243 requires only 0.1µF capacitors in 3.3V operation, and can operate from input voltages ranging

from +3.0V ~ +5.5V. It is ideal for 3.3V-only systems, 5.0V-only systems, or mixed 3.3V and 5.0V systems that

require true RS-232 performance.

The UTC UT13243 includes one complementary always-active receiver that can monitor an external device (such as

a modem) in shutdown, without forward biasing the protection diodes in a UART that may have V_CCcompletely

removed.
