Overview
UNISONIC TECHNOLOGIES CO.
, LTD UT3243 +3.
0V TO +5.
5V POWER SUPPLY, 235KBPS, MULTICHANNAEL RS-232 LINE DRIVERS/RECEIVERS CMOS IC SSOP-28  DESCRIPTION TSSOP-28 The UTC UT3243 consists of 3 drivers and 5 receivers.
It meets ElA/TIA-232 and V.
28/V.
24 specifications, it intended for notebook 1 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 QFN-32(5×5) guaranteed data rate of 120kbps provides compatibility with popular software for communicating with PCs.
The UTC UT3243 achieves 1µA supply current in shutdown condition.
When the UT3243 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 UT3243 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 UT3243 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 VCC completely removed.
