The major difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in IEC 61000-4-2 because series resistance is
lower in the IEC 61000-4-2 model. Hence, the ESD with-
stand voltage measured to IEC 61000-4-2 is generally
lower than that measured using the Human Body Model.
Figure 10c shows the IEC 61000-4-2 model, and Figure
10d shows the current waveform for IEC 61000-4-2 ESD
Contact Discharge test.
Machine Model
The machine model for ESD tests all pins using a
200pF storage capacitor and zero discharge resis-
tance. The objective is to emulate the stress caused
when I/O pins are contacted by handling equipment
during test and assembly. Of course, all pins require
this protection, not just RS-485 inputs and outputs.
Applications Information
256 Transceivers on the Bus
The standard RS-485 receiver input impedance is 12k
Ω
(1-unit load), and the standard driver can drive up to 32-
unit loads. The MAX13080E family of transceivers has a
1/8-unit load receiver input impedance (96k
Ω), allowing
up to 256 transceivers to be connected in parallel on one
communication line. Any combination of these devices,
as well as other RS-485 transceivers with a total of 32-
unit loads or fewer, can be connected to the line.
Reduced EMI and Reflections
The MAX13080E/MAX13081E/MAX13082E feature
reduced slew-rate drivers that minimize EMI and
reduce reflections caused by improperly terminated
cables, allowing error-free data transmission up to
250kbps. The MAX13083E/MAX13084E offer higher dri-
ver output slew-rate limits, allowing transmit speeds up
to 500kbps. The MAX13089E with SRL = VCC or uncon-
nected are slew-rate limited. With SRL unconnected,
the MAX13089E error-free data transmission is up to
250kbps. With SRL connected to VCC, the data transmit
speeds up to 500kbps.
