WebThe 5 V TTL high level is too high for the LVTTL to handle ( > 3.3 V). This could cause permanent damage to the LVTTL chip. Another possible problem would be a system with a 2.5 V IC driving a 5 V CMOS device. The logic high level from the 2.5 V device is not high enough for it to register as a logic high on the 5 V CMOS input (VIH MIN = 3.5 V). WebMay 29, 2010 · TTL modulation is based on TTL signals. A TTL signal is a series of square wave pulses created by cycling the voltage between either 0 (low) or 5V (high) A laser with TTL modulation uses these signals as triggers to turn the laser on and off (more or less, but the actual workings are a little more complex than this). guitar\u0027s w6
