1 MX48/MX483/MX48/ MX487 MX49/MX487 Low-Power, Slew-ate-Limited S-48/S-4 Traceivers General escription The MX48, MX483, MX48, MX487 MX49, and MX487 are low-power traceivers for S-48 and S- 4 communication. Each part contai one driver and one receiver. The MX483, MX487, MX488, and MX489 feature reduced slew-rate drivers that minimize EMI and reduce reflectio caused by improperly terminated cables, thus allowing error-free data tramission up to kbps. The driver slew rates of the MX48, MX48, MX49, MX49, and MX487 are not limited, allowing them to tramit up to.mbps. These traceivers draw between µ and µ of supply current when unloaded or fully loaded with disabled drivers. dditionally, the MX48, MX483, and MX487 have a low-current shutdown mode in which they coume only.µ. ll parts operate from a single supply. rivers are short-circuit current limited and are protected agait excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The MX487 and MX487 feature quarter-unit-load receiver input impedance, allowing up to 8 MX487/ MX487 traceivers on the bus. Full-duplex communicatio are obtained using the MX488 MX49, while the MX48, MX483, MX48, MX487, and MX487 are designed for half-duplex applicatio. pplicatio Low-Power S-48 Traceivers Low-Power S-4 Traceivers Level Tralators Traceivers for EMI-Seitive pplicatio Industrial-Control Local rea Networks Next Generation evice Features For Fault-Tolerant pplicatio MX343: ±8 Fault-Protected, Fail-Safe, /4 Unit Load, +3.3, S-48 Traceiver MX344E MX3444E: ±k ES-Protected, ±6 Fault-Protected, Mbps, Fail-Safe, S-48/J78 Traceivers For Space-Cotrained pplicatio MX346 MX3464: +, Fail-Safe, Mbps, Profibus S-48/S-4 Traceivers MX336: +3.3, High-Speed, S-48/S-4 Traceiver in a SOT3 Package MX38E MX384E: ±k ES-Protected, Mbps, +3 to +., SOT3, S-48/S-4, True Fail-Safe eceivers MX393/MX394/MX39: Mbps, +3.3, SOT3, S-48/S-4 Tramitters For Multiple Traceiver pplicatio MX33E MX333E: ±k ES-Protected, +3.3, Quad S-4 Tramitters For Fail-Safe pplicatio MX38 MX389: Fail-Safe, High-Speed (Mbps), Slew-ate-Limited S-48/S-4 Traceivers For Low-oltage pplicatio MX3483E/MX348E/MX3486E/MX3488E/ MX349E/MX349E: +3.3 Powered, ±k ES-Protected, Mbps, Slew-ate-Limited, True S-48/S-4 Traceivers Ordering Information appears at end of data sheet.

MX489/MX49 Pin Configuration and Typical Operating Circuit pplicatio Information The MX48/MX483/MX48/MX487 MX49 and MX487 are low-power traceivers for S-48 and S- 4 communicatio. The MX48, MX48, MX49, MX49, and MX487 can tramit and receive at data rates up to.mbps, while the MX483, MX487, MX488, and MX489 are specified for data rates up to kbps. The MX488 MX49 are full-duplex traceivers while the MX48, MX483, MX48, MX487, and MX487 are half-duplex. In addition, river Enable (E) and eceiver Enable (E) pi are included on the MX48, MX483, MX48, MX487, MX489, MX49, and MX487. When disabled, the driver and receiver outputs are high impedance. MX487/MX487: 8 Traceivers on the us The 48kΩ, / 4 -unit-load receiver input impedance of the MX487 and MX487 allows up to 8 traceivers on a bus, compared to the -unit load (kω input impedance) of standard S-48 drivers (3 traceivers maximum). ny combination of MX487/ MX487 and other S-48 traceivers with a total of 3 unit loads or less can be put on the bus. The MX48/MX483/MX48 and MX488 MX49 have standard kω eceiver Input impedance. 8 Maxim Integrated

The devices will not shut down unless both the driver and receiver are disabled. In shutdown, the devices typically draw only.µ of supply current. E and E may be driven simultaneously; the parts are guaranteed not to enter shutdown if E is high and E is low for less than. If the inputs are in this state for at least 6, the parts are guaranteed to enter shutdown. For the MX48, MX483, and MX487, the th and tl enable times assume the part was not in the lowpower shutdown state (the MX48/MX488 MX49 and MX487 can not be shut down). The th(shn) and tl(shn) enable times assume the parts were shut down (see Electrical Characteristics). It takes the drivers and receivers longer to become enabled from the low-power shutdown state (th(shn), tl(shn)) than from the operating mode (th, tl). (The parts are in operating mode if the E, E inputs equal a logical, or, or,.) Figure 3. river Output Waveform and FFT Plot of MX483/ MX487 MX489 Tramitting a khz Signal river Output Protection Excessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. foldback current limit on the output stage provides immediate protection agait short circuits over the whole common-mode voltage range (see Typical Operating Characteristics). In addition, a thermal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively. Propagation elay Many digital encoding schemes depend on the difference between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 8 using Figure 4 s test circuit. The difference in receiver delay times, t PLH - t PHL, is typically under 3 for the MX48, MX48, MX49, MX49, and MX487 and is typically less than for the MX483 and MX487 MX489. The driver skew times are typically ( max) for the MX48, MX48, MX49, MX49, and MX487, and are typically (8 max) for the MX483 and MX487 MX489. Maxim Integrated
