±15kV ESD-Protected, 3.3V Quad RS-422 Transmitters

1 19-2671; Rev 0; 10/02. 15kv ESD- protected , quad RS-422 Transmitters General Description Features MAX3030E MAX3033E. The MAX3030E MAX3033E family of quad RS-422 Meet TIA/EIA-422-B ( RS-422 ) and ITU-T Transmitters send digital data transmission signals over Recommendation twisted-pair balanced lines in accordance with TIA/EIA- 422-B and ITU-T standards. All transmitter outputs 15kv ESD Protection on Tx Outputs are protected to 15kv using the Human Body Model. Hot-Swap Functionality The MAX3030E MAX3033E are available with either a 2 Mbps or 20 Mbps guaranteed baud rate. The 2 Mbps Guaranteed 20 Mbps Data Rate (MAX3030E, baud rate Transmitters feature slew-rate-limiting to mini- MAX3032E).

2 Mize EMI and reduce reflections caused by improperly Slew-Rate-Controlled 2 Mbps Data Rate terminated cables. (MAX3031E, MAX3033E). The 20 Mbps baud rate Transmitters feature low-static current consumption (ICC < 100 A), making them ideal Available in 16-Pin TSSOP and Narrow SO. for battery-powered and power-conscious applications. Packages They have a maximum propagation delay of 16ns and a Low-Power Design (<330 W, VCC = Static). part-to-part skew less than 5ns, making these devices ideal for driving parallel data. The MAX3030E + Operation MAX3033E feature hot-swap capability that eliminates Industry-Standard Pinout false transitions on the data cable during power-up or hot insertion.

3 Thermal Shutdown The MAX3030E MAX3033E are low-power, ESD-pro- tected, pin-compatible upgrades to the industry-stan- dard 26LS31 and SN75174. They are available in space-saving 16-pin TSSOP and SO packages. Applications Ordering Information Telecom Backplanes Interface PART TEMP RANGE PIN-PACKAGE. MAX3030 ECSE 0 C to +70 C 16 SO (Narrow).
