The MAX3040–MAX3045 is a family of 5V quad RS-
485/RS-422 transmitters designed for digital data trans-
mission over twisted-pair balanced lines. All transmitter
outputs are protected to ±10kV using the Human Body
Model. In addition the MAX3040–MAX3045 withstand
±4kV per IEC 1000-4-4 Electrical Fast Transient/Burst
Stressing. The MAX3040/MAX3043 (250kbps) and the
MAX3041/MAX3044 (2.5Mbps) are slew-rate limited
transmitters that minimize EMI and reduce reflections
caused by improperly terminated cables, thus allowing
error-free transmission.
The MAX3040–MAX3045 feature a hot-swap capability*
that eliminates false transitions on the data cable during
power-up or hot insertion. The MAX3042B/MAX3045B
are optimized for data transfer rates up to 20Mbps, the
MAX3041/MAX3044 for data rates up to 2.5Mbps, and
the MAX3040/MAX3043 for data rates up to 250kbps.
The MAX3040–MAX3045 offer optimum performance
when used with the MAX3093E or MAX3095 5V quad
differential line receivers or MAX3094E/MAX3096 3V
quad differential line receivers.
The MAX3040–MAX3045 are ESD-protected pin-compat-
ible, low-power upgrades to the industry-standard
‘SN75174 and ‘DS26LS31C. They are available in space-
saving TSSOP, narrow SO, and wide SO packages.
