TTL Pulse-Width Regulators
Takes logic-level-input signals of unequal duration and transforms these into logic-
level output signals of precisely timed and equal duration.
5 ns minimum input-pulse width, 5 to 500 ns output-pulse width, as selected.
Input-pulse width can vary; output-pulse width remains the same. Precisely timed
output-pulse trailing edge permits trailing-edge timing or gating functions.
