Note:
1. When multiple outputs are switched at the same time, rapidly changing current on the ground and V
CC
paths causes a
voltage to develop across the parasitic inductance of the wire bond and package pins. This occurrence is called
simultaneous switching noise. Atmel’s AT16244 products have minimized this phenomenon as shown on the graph.
Output data is for 15 outputs switching simultaneously at a frequency of 1 MHz. The ground data is measured on the one
remaining output, which is set to logic low and will reflect any device ground movement.
2. As on the graph for Ground Bounce, a similar condition occurs for low to high transitions. Output data is for 15 outputs
switching simultaneously at a frequency of 1 MHz. V
CC
droop is measured on the one remaining output pin, which is set
to a logic high. This output will reflect any movement on the device V
CC
.
