Applications Information
Layout Recommendations
Use standard high-speed layout practices when
laying out a board with the MAX14591. For example, to
minimize line coupling, place all other signal lines not con-
nected to the device at least 1x the substrate height of the
PCB away from the input and output lines of the device.
Extended ESD
ESD protection structures are incorporated on all pins to
protect against electrostatic discharges up to ±2kV (HBM)
encountered during handling and assembly. After an ESD
event, the device continues to function without latchup.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
setup, test methodology, and test results.
Human Body Model
Figure 5 shows the Human Body Model. Figure 6 shows
the current waveform it generates when discharged
into a low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest that is
then discharged into the device through a 1.5kI resistor.
