Product Details The ADM213E is one in a family of robust RS-232 and V.28 interface devices which operates from a single +5 V power supply. These products are suitable for operation in harsh electrical environments and are compliant with the EU directive on EMC (89/336/ EEC). Both the level of emissions and immunity are in compliance. EM immunity includes ESD protection in excess of ±15 kV on all I-O lines (1000-4-2), Fast Transient Burst protection (1000-4-4) and Radiated Immunity (1000-4-3). EM emissions include radiated and conducted emissions as required by Information Technology Equipment EN55022, CISPR22. All devices fully conform to the EIA-232E and CCITT V.28 specifications and operate at data rates up to 230 kbps. Shutdown and Enable control pins are provided on some of the products. The shutdown function on the ADM211E disables the charge pump and all transmitters and receivers. On the ADM213E the charge pump, all transmitters, and three of the five receivers are disabled. The remaining two receivers remain active thereby allowing monitoring of peripheral devices. This feature allows the device to be shut down until a peripheral device begins communication. The active receivers can alert the processor which can then take the ADM213E out of the shutdown mode. Operating from a single +5 V supply, four external 0.1 µF capacitors are required. The ADM206E is available in a 24-pin SO package. The ADM207E and ADM208E are available in 24-pin DIP, SO, SSOP and TSSOP packages. The ADM211E and ADM213E are available in 28-pin SO, SSOP and TSSOP packages. All products are backward compatible with earlier ADM2xx products facilitating easy upgrading of older designs. ### Features and Benefits
The SP213EHCA-L is an enhanced multi-channel high performance RS232 Line Transceiver with improved electrical performance. The SP200E is pin-to-pin compatible with our previous SP200 family as well as popular industry standards. As with the original SP200 family, all models in this series feature low-power CMOS construction and Sipex-patented on-board charge pump circuitry to generate the ±10V RS-232 voltage levels, using 0.1µF charge pump capacitors to save board space. Enhancements include lower power supply current at 3mA typical (no load) and superior ESD performance. The ESD tolerance has been improved on this family to over ±15kV for both human body model and IEC1000-4-2 air discharge test methods.
The MAX213IDBR is a RS-232 multichannel Line Driver/Receiver consists of four line drivers, five line receivers and a dual charge-pump circuit with ±15kV ESD protection pin-to-pin (serial-port connection pins, including GND). The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The charge pump and four small external capacitors allow operation from a single 5V supply. The device operates at data signalling rates up to 120kbps and a maximum of 30V/µs driver output slew rate. The MAX213 has an active-low shutdown (SHDN) and an active-high enable control (EN). In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, V- is pulled to GND and the transmitter outputs are disabled. This reduces supply current typically to 1µA. Two receivers of the MAX213 are active during shutdown.
