Ordering Information/Selector Guide
General Description
The MAX14840E/MAX14841E are +3.3V ESD-protected
transceivers intended for half-duplex RS-485 communi-
cation up to 40Mbps. These transceivers are optimized
for high speeds over extended cable runs while maximiz-
ing tolerance to noise.
The MAX14840E features symmetrical fail-safe and larg-
er receiver hysteresis, providing improved noise rejec-
tion and improved recovered signals in high-speed and
long cable applications. The MAX14841E has true fail-
safe receiver inputs guaranteeing a logic-high receiver
output when inputs are shorted or open.
The MAX14840E/MAX14841E transceivers draw 1.5mA
(typ) supply current when unloaded or when fully loaded
with the drivers disabled. Hot-swap capability eliminates
undesired transitions on the bus during power-up or hot
insertion.
The MAX14840E/MAX14841E are available in 8-pin SO
and small, 8-pin (3mm x 3mm) TDFN-EP packages. Both
devices operate over the -40NC to +125NC automotive
temperature range.
