Product Description
The UM207/208/211/213 are enhanced transceivers intended for use in RS-232 and V.28 serial communication and are particularly suited for those applications where ±12V 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 0.1µF 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 UM211 and UM213 feature a low power shutdown mode, which reduces power supply drain to 1µA. The UM213 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 over ±15kV for both human body mode and IEC61000-4-2 air discharge mode.
The UM207/208 series are available in SOP24, SSOP24 and TSSOP24 packages, the UM211/213 are available in SOP28, SSOP28 and TSSOP28 packages.
