Configurations
The MAX213E’s receiver propagation delay is typically
0.5μs in normal operation. In shutdown mode,
propagation delay increases to 4μs for both rising and
falling transitions. The MAX213E’s receiver inputs have
approximately 0.5V hysteresis, except in shutdown,
when receivers R4 and R5 have no hysteresis.
When entering shutdown with receivers active, R4 and
R5 are not valid until 80μs after
SHDN
is driven low.
When coming out of shutdown, all receiver outputs are
invalid until the charge pumps reach nominal voltage
levels (less than 2ms when using 0.1μF capacitors).
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures
are incorporated on all pins to protect against
electrostatic discharges encountered during handling
and assembly. The driver outputs and receiver inputs
have extra protection against static electricity. Maxim’s
engineers developed state-of-the-art structures to
protect these pins against ESD of ±15kV without
damage. The ESD structures withstand high ESD in all
states: normal operation, shutdown, and powered
down. After an ESD event, Maxim’s E versions keep
working without latchup, whereas competing RS-232
products can latch and must be powered down to
remove latchup.
ESD protection can be tested in various ways; the
transmitter outputs and receiver inputs of this product
family are characterized for protection to the following
limits:
1) ±15kV using the Human Body Model
2) ±8kV using the contact-discharge method specified
in IEC1000-4-2
3) ±15kV using IEC1000-4-2’s air-gap method.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test set-up, test methodology, and test results.
Human Body Model
Figure 6a shows the Human Body Model, and Figure
6b 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, which is then discharged into the test device
through a 1.5k
resistor.
