SOP-28
DESCRIPTION
The UTC UT213 consists of 4 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 UT213 has an active-low shutdown and an active-high
receiver enable control. Two receivers of the UTC 213 are active, allowing
the ring indicator(RI)to be monitored easily using only 75uW power.
The UTC UT213 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.
FEATURES
* Operates With 3.0V~5.5V Power Supply
* Four Drivers and Five Receivers
* Operates Up To 120 kbps
* Designed to Transmit at a Data Rate of 120 kbps
* Low Standby Current (15µA Typical)
* External Capacitors (4*0.1µF)
* Accepts 5.0V Logic Input With 3.3V Supply
* Serial-Mouse Drivability
* Exceeds ±8KV ESD Protection(HBM) for RS-232 I/O Pins
