Test Circuit
Output Delay Circuit
between outputs and is intended to have the effect of reducing switching noise by reducing the di/dt when all
outputs are ON or OFF at the same time.
A delay circuit is built-in to each output, with the equivalent as illustrated below.
There is a switching time lag (20 ns typ.) between adjacent outputs. This is designed for high speed switching
