high threshold logic (HTL)

High Threshold Logic

(HTL) are logics with a higher response threshold, which ensure increased noise immunity.A higher response threshold means that the threshold values for "LO" and "HI" have a greater voltage distance to each other than is the case with other logics. In DTL

logicsor DL logics, this is achieved by Zener diodes

. HTL logics operate with a higher supply voltage and can be usefully employed wherever the logics are exposed to high interference voltages and noise.
