High Threshold Logic : ウィキペディア英語版 | High Threshold Logic
High Threshold Logic (HTL) is a variant of DTL which is used in such environments where noise is very high. == Operation == The threshold values at the input to a logic gate determine whether a particular input is interpreted as a logic 0 or a logic 1.(e.g. anything less than 1 V is a logic 0 and anything above 3 V is a logic 1. In this example, the threshold values are 1V and 3V). HTL incorporates Zener diodes to create a large offset between logic 1 and logic 0 voltage levels.These devices usually ran off a 15 V power supply and were found in industrial control, where the high differential was intended to minimize the effect of noise.
