immediate protection against short circuits over the
whole common-mode voltage range (see the Typical
Operating Characteristics). Additionally, a thermal shut-
down circuit forces the driver outputs into a high-imped-
ance state if the die temperature exceeds +160NC (typ).
Low-Power Shutdown Mode
Low-power shutdown mode is initiated by bringing RE
high and DE low. In shutdown, the devices draw less
than 10FA 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 800ns, the parts are guaranteed to enter shutdown.
Typical Applications
The MAX14840E/MAX14841E transceivers are designed
for bidirectional data communications on multipoint bus
transmission lines. Figure 15 shows a typical network
application circuit. To minimize reflections, terminate the
line at both ends with its characteristic impedance and
keep stub lengths off the main line as short as possible.
