The UM213 is enhanced transceivers intended for use in RS-232 and V.28 serial communication and are particularly suited for those applications where ±6V is not available. These devices feature very low power consumption and 5V single supply operation making them ideal for space-constrained applications. With integrated charge pump circuitry and small 0.1礔 charge pump capacitors, these devices can fully meet RS-232 voltage levels. A slow rate limited transmitter circuit improves data integrity. The receiver features hysteresis to greatly improve noise rejection. The UM213 features a low power shutdown mode, which reduces power supply drain to 1礎. The UM213 also includes two receivers that remain active during shutdown to monitor for signal activity.
The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 250kbps when loaded in accordance with the EIA/TIA-232E specification Driver output and receiver input pins are protected against ESD to ±8kV for human body mode and ±15kV for IEC61000-4-2 air discharge mode.
