Actually, the standard specifies an allowable voltage range from +/- 3V to 15V, with receivers required to tolerate up to 25V. Voltages less than +/- 3V to are undefined. In the days of TTL design, it was common to use the +/- 12V rails to power a LM1488 driver. Those of us who did interface design back in those days used to complain a lot about substandard implementations which didn't work with certain other devices. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
