1 9-22; ev ; /3 General escription The MX4, MX43, MX45, MX47 MX49, and MX47 are low-power traceivers for S-45 and S- 422 communication. Each part contai one driver and one receiver. The MX43, MX47, MX4, and MX49 feature reduced slew-rate drivers that minimize EMI and reduce reflectio caused by improperly terminated cables, thus allowing error-free data tramission up to 25kbps. The driver slew rates of the MX4, MX45, MX49, MX49, and MX47 are not limited, allowing them to tramit up to 2.5Mbps. These traceivers draw between 2µ and 5µ of supply current when unloaded or fully loaded with disabled drivers. dditionally, the MX4, MX43, and MX47 have a low-current shutdown mode in which they coume only.µ. ll parts operate from a single 5 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 MX47 and MX47 feature quarter-unit-load receiver input impedance, allowing up to 2 MX47/ MX47 traceivers on the bus. Full-duplex communicatio are obtained using the MX4 MX49, while the MX4, MX43, MX45, MX47, and MX47 are designed for half-duplex applicatio. pplicatio Low-Power S-45 Traceivers Low-Power S-422 Traceivers Level Tralators Traceivers for EMI-Seitive pplicatio Industrial-Control Local rea Networks Next Generation evice Features For Fault-Tolerant pplicatio MX343: ± Fault-Protected, Fail-Safe, /4 Unit Load, +3.3, S-45 Traceiver MX344E MX3444E: ±5k ES-Protected, ±6 Fault-Protected, Mbps, Fail-Safe, S-45/J7 Traceivers For Space-Cotrained pplicatio MX346 MX3464: +5, Fail-Safe, 2Mbps, Profibus MX3362: +3.3, High-Speed, S-45/S-422 Traceiver in a SOT23 Package MX32E MX324E: ±5k ES-Protected, 52Mbps, +3 to +5.5, SOT23, S-45/S-422, True Fail-Safe eceivers MX3293/MX3294/MX3295: 2Mbps, +3.3, SOT23, S-55/S-422 Tramitters For Multiple Traceiver pplicatio MX33E MX333E: ±5k ES-Protected, +3.3, Quad S-422 Tramitters For Fail-Safe pplicatio MX3 MX39: Fail-Safe, High-Speed (Mbps), Slew-ate-Limited S-45/S-422 Traceivers For Low-oltage pplicatio MX343E/MX345E/MX346E/MX34E/ MX349E/MX349E: +3.3 Powered, ±5k ES-Protected, 2Mbps, Slew-ate-Limited, True Selection Table PT NUME MX4 MX43 MX45 MX47 MX4 MX49 MX49 MX49 MX47 HLF/FULL UPLEX Half Half Half Half Full Full Full Full Half T TE (Mbps) SLEW-TE LIMITE LOW-POWE SHUTOWN Ordering Information appears at end of data sheet.

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. and may be driven simultaneously; the parts are guaranteed not to enter shutdown if is high and is low for less than 5. If the inputs are in this state for at least 6, the parts are guaranteed to enter shutdown. For the MX4, MX43, and MX47, the th and tl enable times assume the part was not in the lowpower shutdown state (the MX45/MX4 MX49 and MX47 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).

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 5 using Figure 4 s test circuit. The difference in receiver delay times, tplh - tphl, is typically under 3 for the MX4, MX45, MX49, MX49, and MX47 and is typically less than for the MX43 and MX47 MX49. The driver skew times are typically 5 ( max) for the MX4, MX45, MX49, MX49, and MX47, and are typically ( max) for the MX43 and MX47 MX49. MX4/MX43/MX45/MX47 MX49/MX47
