UM3483E/UM3486E 3V to 5.5V-Powered, ±15kV ESD-Protected, Slew-Rate-Limited, True RS-485 Transceivers UM3483E/UM3486E SOP8/DIP8 General Description The UM3483E, UM3486E are 3V to 5.5V-powered, ±15kV ESD-protected, slew-rate-limited differential transceivers which provide full RS485 compatibility. Each part contains one driver and one receiver, which is designed for data transmission with extended common mode range (-7V to 12V). The UM3483E features slew-rate-limited driver which minimizes EMI and reduces reflections resulted from improperly terminated cables. The UM3483E allows up to 500kbps error-free data transmission, while the partially slew-rate-limited UM3486E transmits at data rates up to 2.5Mbps. The UM3483E, UM3486E also feature enhanced electrostatic discharge (ESD) protection. All of the transmitter outputs and receiver inputs are protected to ±15kV using IEC61000-4-2 Air-Gap Discharge, ±15kV using the Human Body Model and ±8kV using IEC61000-4-2 Contact Discharge. Drivers are short-circuit current limited. When the driver outputs are placed into a high-impedance state by thermal shutdown circuitry, drivers are protected against excessive power dissipation. And the fail-safe feature of the receiver input guarantees a logic-high output if both inputs are open, shorted or idle. Both parts have power up/down mode, the glitch-free driver outputs permit live insertion or removal of the transceiver into/from the data bus. The CMOS design offers significant power savings without sacrificing ruggedness against overload or ESD damage. The typical quiescent current is only 300μA during operation and 1μA in shutdown mode. The UM3483E, UM3486E are intended for half-duplex communication and are available in SOP8 and DIP8 packages.

Typical Half-Duplex RS-485 Network Detail Description The UM3483E, UM3486E are low-power transceivers for RS-485 communications. The UM3483E can transmit and receive at data rates up to 500kbps, and the UM3486E at up to 2.5Mbps. The UM3483E, UM3486E are half-duplex. Driver Enable (DE) and Receiver Enable ______ (R E ) pins are included on the UM3483E, UM3486E. When disabled, the driver and receiver outputs are high impedance. Fail-Safe The UM3483E, UM3486E guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver threshold between -50mV and -200mV. If the differential receiver input voltage (A-B) is greater than or equal to -50mV, RO is logic high. If A-B is less than or equal to -200mV, RO is logic low. In the case of a terminated bus with all transmitters disabled, the receiver’s differential input voltage is pulled to 0V by the termination. With the receiver thresholds of the UM3483E, UM3486E, this results in a logic high with a 50mV minimum noise margin. Unlike previous fail-safe devices, the -50mV to -200mV threshold complies with the ±200mV EIA/TIA-485 standard. ±15kV ESD Protection As with all Union devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs of the UM3483E, UM3486E have extra protection against static electricity. Union’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD-protected pins are tested with reference to the ground pin in a power-down condition. They are tested to ±15kV using the Human Body Model. Applications Information 256 Transceivers on the Bus The standard RS-485 receiver input impedance is 12kΩ (one unit load), and the standard driver can drive up to 32 unit loads. The Union family of transceivers have a 1/8 unit load receiver input impedance (96kΩ), allowing up to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices and/or other RS-485 transceivers with a total of 32 unit loads or less can be connected to the line. ________________________________________________________________________ http://www.union-ic.com Rev.03 Dec.2014 14/18 UM3483E/UM3486E Reduced EMI and Reflections The UM3483E, UM3486E are slew-rate-limited, minimizing EMI and reducing reflections caused by improperly terminated cables. In general, a transmitter’s rise time relates directly to the length of an unterminated stub, which can be driven with only minor waveform reflections. The following equation expresses this relationship conservatively: Length=tRISE/(10×1.5ns/ft) Where tRISE is the transmitter’s rise time. A system can work well with longer unterminated stubs, even with severe reflections, if the waveform settles out before the UART samples them. Low-Power Shutdown Mode ______ Low-power shutdown mode is initiated by bringing both R E high and DE low. In shutdown, the ______ device typically draws only 1μA of supply current. R E and DE may be driven simultaneously; ______ the parts are guaranteed not to enter shutdown if R E is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown. Enable times tPZH and tPZL in the Switching Characteristics tables assume the part was not in a low-power shutdown state. Enable times tPSH and tPSL assume the parts were shut down. It takes drivers and receivers longer to become enabled from low-power shutdown mode (tPSH, tPSL) than from driver/receiver-disable mode (tPZH, tPZL). Driver Output Protection Two mechanisms prevent excessive output current and power dissipation caused by faults or bus contention. First, a foldback current limit on the output stage, provides immediate protection against short circuits over the whole common-mode voltage range. Second, a thermal shutdown circuit, forces the driver outputs into a high-impedance state if the die temperature becomes excessive. Propagation Delay Skew time is simply the difference between the low-to-high and high-to-low propagation delay. Small driver/receiver skew times help maintain a symmetrical mark-space ratio (50% duty cycle). The receiver skew time, |tRPLH - tRPHL|, is under 10ns (20ns for the UM3483E). The driver skew times 12ns for the UM3486E, and typically under 50ns for the UM3483E. Typical Applications The UM3483E, UM3486E transceivers are designed for bidirectional data communications on multipoint bus transmission lines. To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths of the main line should be kept as short as possible. The slew-rate-limited UM3483E and the partially slew-rate-limited UM3486E are more tolerant of imperfect termination. ________________________________________________________________________ http://www.union-ic.com Rev.03 Dec.2014 15/18 UM3483E/UM3486E Package Information SOP8 Outline Drawing c L D E E1 Symbol 1 2 θ e Top View A A2 End View A1 b Side View A A1 A2 b c D E E1 e L θ DIMENSIONS MILLIMETERS INCHES Min Max Min Max 1.350 1.750 0.053 0.069 0.100 0.250 0.004 0.010 1.350 1.550 0.053 0.061 0.33 0.51 0.013 0.020 0.170 0.250 0.006 0.010 4.700 5.100 0.185 0.200 3.800 4.000 0.150 0.157 5.800 6.200 0.228 0.244 1.270 (BSC) 0.050 (BSC) 0.400 1.270 0.016 0.050 0° 8° 0° 8° 4.95 1.30 Land Pattern 1.27 0.50 NOTES: 1.
