MAX3040MAX3045 19-2143 Rev 1 12/01 10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters General Description Features The MAX3040MAX3045 is a family of 5V quad RS- ESD Protection: 10kVHuman Body Model 485/RS-422 transmitters designed for digital data trans- Single +5V Operation mission over twisted-pair balanced lines. All transmitter Guaranteed Device-to-Device Skew outputs are protected to 10kV using the Human Body (MAX3040/MAX3041/MAX3043/MAX3044) Model. In addition the MAX3040MAX3045 withstand 4kV per IEC 1000-4-4 Electrical Fast Transient/Burst Pin-Compatible with SN75174, 26LS31C and Stressing. The MAX3040/MAX3043 (250kbps) and the LTC487 MAX3041/MAX3044 (2.5Mbps) are slew-rate limited Hot-Swappable for Telecom Applications transmitters that minimize EMI and reduce reflections Up to 20Mbps Data Rate (MAX3042B/MAX3045B) caused by improperly terminated cables, thus allowing error-free transmission. Slew-Rate Limited (Data Rates at 2.5Mbps and 250kbps) The MAX3040MAX3045 feature a hot-swap capability that eliminates false transitions on the data cable during 2nA Low-Power Shutdown Mode power-up or hot insertion. The MAX3042B/MAX3045B 1mA Operating Supply Current are optimized for data transfer rates up to 20Mbps, the MAX3041/MAX3044 for data rates up to 2.5Mbps, and 4kV EFT Fast Transient Burst Immunity per IEC the MAX3040/MAX3043 for data rates up to 250kbps. 1000-4-4 The MAX3040MAX3045 offer optimum performance Level 2 Surge Immunity per IEC 1000-4-5, when used with the MAX3093E or MAX3095 5V quad Unshielded Cable Model differential line receivers or MAX3094E/MAX3096 3V Ultra-Small 16-Pin TSSOP, 16-Pin Narrow SO, and quad differential line receivers. Wide 16-Pin SO The MAX3040MAX3045 are ESD-protected pin-compat- ible, low-power upgrades to the industry-standard Ordering Information SN75174 and DS26LS31C. They are available in space- saving TSSOP, narrow SO, and wide SO packages.
