CH340g USB to TTL IC

In addition, it is compatible with RS-422. The driver and receiver outputs feature TRI-STATE capability, for the driver outputs over the entire common mode range of 12V to ?7V. Bus contention or fault situations that cause excessive power dissipation within the device are handled by a thermal shutdown circuit, which forces the driver outputs into the high impedance state. DC specifications are guaranteed over the 0 to 70?C temperature and 4.75V to 5.25V supply voltage range.

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 charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. The devices operate at data signalling rates up to 250 kbit/s and a maximum of 30-V/?s driver output slew rate.

MAX485 is a low power transceivers for RS485 and RS422 communication. MAX485 contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit up to 2.5Mbps.

These transceivers draw between 120?A and 500?A of supply current when unloaded or fully loaded with disabled drivers.?MAX485ESA RS422 RS485 IC?operates from a single 5V supply. Drivers are short circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.

The?MCP2551?is a high-speed?Controller Area Network?(CAN), fault-tolerant?device that serves as the interface between a?CAN?protocol controller?and the physical bus. The MCP2551?device provides differential transmit and receive?capability for the CAN protocol controller, and is fully?compatible with the ISO-11898 standard, including 24V?requirements. It will operate at speeds of up to 1 Mb/s.

Typically, each node in a CAN system must have a?device to convert the digital signals generated by a?CAN controller to signals suitable for transmission over?the bus cabling (differential output). It also provides a?buffer between the CAN controller and the high-voltage?spikes that can be generated on the CAN bus by?outside sources (EMI, ESD, electrical transients, etc.).
