MAX3040 Description

The MAX3040 is a family of 5V quad RS-485/RS-422 transmitters designed for digital data transmission over twisted-pair balanced lines. All transmitter outputs are protected to ±10kV using the Human Body Model. The MAX3040 (250kbps) are slew-rate limited transmitters that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free transmission.

The MAX3040 feature a hot-swap capability that eliminates false transitions on the data cable during power-up or hot insertion. The MAX3040 for data rates up to 250kbps. The MAX3040 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 are ESD-protected pin-compatible, low-power upgrades to the industry-standard 'SN75174 and 'DS26LS31C. They are available in space-saving TSSOP, narrow SO, and wide SO packages.
