Figure 18’s high-frequency harmonic components are
much lower in amplitude, compared with Figure 17’s,
and the potential for EMI is significantly reduced. Figure
19 shows the same signal displayed for a MAX3060E
transmitting under the same conditions. Figure 19’s
high-frequency harmonic components are even lower.
In general, a transmitter’s rise time relates directly to the
length of an unterminated stub, which can be driven with
only minor waveform reflections. The following equation
expresses this relationship conservatively:
Length = tRISE / (10 x 1.5ns/ft)
where tRISE is the transmitter’s rise time.
For example, the MAX3060E’s rise time is typically
1850ns, which results in excellent waveforms with a stub
length up to 123ft. A system can work well with longer
unterminated stubs, even with severe reflections, if the
waveform settles out before the UART samples them.
Low-Power Shutdown Mode
Low-power shutdown mode is initiated by bringing both
RE high and DE low. In shutdown, the devices typically
draw only 1nA of supply current.
RE and DE can be driven simultaneously. The parts are
guaranteed not to enter shutdown if RE is high and DE is
low for less than 50ns. If the inputs are in this state for at
least 600ns, the parts are guaranteed to enter shutdown.
Enable times t_ZH and t_ZL in the Switching Char-
acteristics tables assume the part was not in a low-
power shutdown state. Enable times t_ZH(SHDN) and
t_ZL(SHDN) assume the parts were shut down. It takes
drivers and receivers longer to become enabled from
low-power shutdown mode (t_ZH(SHDN), t_ZL(SHDN))
than from driver/receiver-disable mode (t_ZH, t_ZL).
Driver Output Protection
Two mechanisms prevent excessive output current and
power dissipation caused by faults or by bus con-
tention. The first, a foldback current limit on the output
stage, provides protection after a 20s delay against
short circuits over the whole common-mode voltage
range (see Typical Operating Characteristics). The sec-
ond, a thermal shutdown circuit, forces the driver out-
puts into a high-impedance state if the die temperature
becomes excessive.
