鹵15kV ESD-Protected, Fail-Safe, 20Mbps, Slew-Rate-
Limited RS-485/RS-422 Transceivers in a SOT
General Description
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 cir-
cuitry 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
鹵15kV using the Human Body Model.
These transceivers typically draw 910碌A(chǔ) of supply
current when unloaded, or 790碌A(chǔ) when fully loaded
with the drivers disabled.
All devices have a 1/8-unit-load receiver input imped-
ance that allows up to 256 transceivers on the bus. These
devices are intended for half-duplex communication.
