UCC3750DW

ISO3082 is an isolated half duplex differential line transceivers for TIA/EIA 485/422 applications. These devices are ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500 VRMS of isolation for 60 s per UL 1577 between the bus-line transceiver and the logic-level interface.

Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuits.

The?MAX3232 device?consists of two line drivers, two line receivers, and a dual charge-pump circuit with ?15-kV 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 devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/?s driver output slew rate.

The device reduces external components by integrating the USB termination resistors. The?MCP2200?also has 256 bytes of integrated user EEPROM.The?MCP2200?has eight general purpose input/output pins. Four pins have alternate functions to indicate USB and communication status.
