CH340g USB to TTL IC

MAX232 is a communication IC. It is used to convert TTL Signals to RS232 Signal and vice versa.?MAX232?provides RS-232 voltage level outputs (approx. ? 7.5 V) from a single 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.

The receivers reduce RS-232 inputs (which may be as high as ? 25 V), to standard 5 V TTL levels. These receivers have a typical threshold of 1.3 V, and a typical hysteresis of 0.5 V.

Each part contains one driver and one receiver. The driver slew rates of the MAX485 is not limited, allowing them to transmit up to 2.5Mbps. All parts operate from a single 5V supply.The driver is short-circuit current limited and? 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 MAX485 is designed for half-duplex applications.

The MCP2510 provides immediate CAN support across the entire breadth of Microchip?s 100 PICmicro? microcontrollers, providing a seamless migration path and maximum design flexibility for CAN designs. The?MCP2510 CAN Controller?contains on-board features, such as interrupt capability, message masking and filtering, message prioritization, multi-purpose I/O pins, and multiple transmit/receive buffers which significantly offload the microcontroller overhead required to handle CAN message traffic. Applications for the MCP2510 include motor control, smoke detectors, CO detectors, sensors, meters, automotive electronics, climate control and instrument clusters.
