UM207 Overview
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.
Key Features
- 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
