Output Delay Circuit
Test Circuit7: Switching Characteristics
switching noise by reducing the di/dt when all outputs are ON or OFF at the same time.There is a switching time
lag (20 ns typ.) between adjacent outputs.
This is designed for high speed switching between outputs and is intended to have the effect of reducing
