The MAX3060E/MAX3061E/MAX3062E high-speed
transceivers for RS-485/RS-422 communication contain
one driver and one receiver. These devices feature fail-safe
circuitry, which guarantees a logic-high receiver
output when the receiver inputs are open or shorted.
This means that the receiver output is a logic high if all
transmitters on a terminated bus are disabled (high
impedance). These devices also feature hot-swap circuitry
that eliminates data glitches during hot insertion.
The MAX3060E features slew-rate-limited drivers that
minimize EMI and reduce reflections caused by
improperly terminated cables, allowing error-free data
transmission up to 115kbps. The MAX3061E, also slew-rate
limited, transmits up to 500kbps. The MAX3062E
driver is not slew-rate limited, allowing transmit speeds
up to 20Mbps. All transmitter outputs are protected to
±15kV using the Human Body Model.
These transceivers typically draw 910µA of supply
current when unloaded, or 790µA when fully loaded
with the drivers disabled.
All devices have a 1/8-unit-load receiver input impedance
that allows up to 256 transceivers on the bus. These
devices are intended for half-duplex communication.
