TTL RS232 driver circuit and Protect the PC from direct connection to hazardous voltages

By admin | Published: 11/20/2009
TTL RS232 driver circuit. TTL driver circuit consists of 2 transistors and a few other passive components, a negative voltage for RS232 logic generated by the capacitor C7. TTL to RS232 driver circuit and a variable voltage output driver has a parallel termination impedance to match cable and TTL driver circuit, and provides the best waveform. When driving [...]
