MAX202 RS232 Transceivers ( MAX202CPE ) The MAX202 transceiver is designed for RS232 and V.28 comm unication interfaces where a ±12V supply is not available. On-board charge pumps convert the +5V input to the ±10V needed for RS232 output levels. The drivers and receivers meet all EIA/TIA-232E and CCITTV.28 specifications at a data rate of 20kbits/sec. The device requires just four external capacitors to provide the voltage conversion. Supplied in a 16-pin DIL package (MAX202CPE). MAX232CPE RS-232Transmitter/Receiver ( MAX232CPE ) A dual RS-232 receiver/transmitter that meets all the EIA RS-232C specifications while requiring only a single +5V supply. This significantly simplifies system design by removing the need to provide power supply voltages other than +5V. The IC has two on-board charge pump voltage convertors which generate +10V and -10V power supplies from the single +5V supply.The IC contains four level translators, two of which convert TTL/CMOS input levels into ±9V RS-232 outputs ready for transmission, and two of which convert RS-232 inputs to 5V TTL/CMOS levels. The receivers have a nominal threshold of 1 3V, a typical hysteresis of 0 5V, and can operate with up to ±30V inputs.

Pre-Sensitised Copper-Clad Board ( F/Glass Size1 Single ) · Single and double-sided copper clad SRBP and glass fibre boards coated with a positive photo-resist · Suitable for use with our UV exposure box· Covered with light-proof protective film, which should not be removed until the board is used The PCB should be exposed using our UV exposure box and a circuit overlay transparency. Exposure time will be from 8 to 15 minutes. Mix together 0.5 litres approximately with one teaspoonful of sodium hydroxide (available from most chemists) and pour into a tray (CH38R). Gently rock the exposed PCB in the tray until the unwanted photo resist is dissolved away. Etch the board in a bath of ferric chloride and after rinsing, expose the PCB in the UV box for a further 10 minutes. Wash off all the remaining etch resist in a tray of sodium hydroxide solution.
