19-2143; Rev 1; 12/01 ±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters General Description The MAX3040–MAX3045 is a family of 5V quad RS485/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. 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.

19-2143; Rev 1; 12/01 ±10kV ESD-Protected, Quad 5V RS-485/RS-422 Transmitters General Description The MAX3040–MAX3045 is a family of 5V quad RS485/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. 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-compatible, low-power upgrades to the industry-standard ‘SN75174 and ‘DS26LS31C. They are available in spacesaving TSSOP, narrow SO, and wide SO packages. *Patent pending Features o ESD Protection: ±10kV—Human Body Model o Single +5V Operation o Guaranteed Device-to-Device Skew (MAX3040/MAX3041/MAX3043/MAX3044) o Pin-Compatible with ‘SN75174, ‘26LS31C and LTC487 o Hot-Swappable for Telecom Applications o Up to 20Mbps Data Rate (MAX3042B/MAX3045B) o Slew-Rate Limited (Data Rates at 2.5Mbps and 250kbps) o 2nA Low-Power Shutdown Mode o 1mA Operating Supply Current o ±4kV EFT Fast Transient Burst Immunity per IEC 1000-4-4 o Level 2 Surge Immunity per IEC 1000-4-5, Unshielded Cable Model o Ultra-Small 16-Pin TSSOP, 16-Pin Narrow SO, and Wide 16-Pin SO MAX3040–MAX3045 Ordering Information PART MAX3040 CUE MAX3040CSE MAX3040CWE MAX3040EUE MAX3040ESE TEMP RANGE 0° C to +70 ° C 0° C to +70 ° C 0° C to +70 ° C -40° C to +85 °C -40° C to +85 °C PIN-PACKAGE 16 TSSOP 16 Narrow SO 16 Wide SO 16 TSSOP 16 Narrow SO 16 Wide SO DATA RATE 250kbps 250kbps 250kbps 250kbps 250kbps 250kbps Applications Telecommunications Equipment Industrial Motor Control Transmitter for ESD-Sensitive Applications Hand-Held Equipment Industrial PLCs Networking PART MAX3040 MAX3041 MAX3042B MAX3043 MAX3044 MAX3045B DATA RATE (bps) 250k 2.5M 20M 250k 2.5M 20M MAX3040EWE -40° C to +85 °C Ordering Information continued at end of data sheet.
