40Mbps, +3.3V, RS-485 Half-Duplex

Transceivers

General Description

Features

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 minimiz-

ing tolerance to noise.

S Half-Duplex RS-485 Transceivers

S +3.3V Supply Voltage

S 40Mbps Maximum Data Rate

S Large (170mV) Receiver Hysteresis on

MAX14840E

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.

S Symmetrical Fail-Safe Receiver Input on

MAX14840E

S Fail-Safe Receiver Input (MAX14841E)

S Hot-Swap Capability

S Short-Circuit Protected Outputs

S Thermal Self-Protection

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.

S Low 10µA (max) Shutdown Current

S Extended ESD Protection for RS-485 I/O Pins

±35ꢀV Human Body Model (HBM)

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.
