WebTTL Value Definition. Time-to-live (TTL) is a numerical value used for data validity and expiration. A TTL stands for the amount of time data should remain valid and available before a computing system discards it. For example, it could represent the number of seconds certain data, or a certain data record, is retained or is considered valid. WebVoltage Tolerance of TTL Gate Inputs. TTL gates operate on a nominal power supply voltage of 5 volts, +/- 0.25 volts. Ideally, a TTL “high” signal would be 5.00 volts exactly, and a TTL “low” signal 0.00 volts exactly. However, real TTL gate circuits cannot output such perfect voltage levels, and are designed to accept “high” and ...
