The driver outputs and receiver are always active in these devices. etailed escription The MX14784E/MX14786E/ are ±35kV ES protected S-485 transceivers intended for high-speed, full-duplex communication. These devices operate from a +3.V to +5.5V supply and feature true fail-safe circuitry, guaranteeing a logic high on the receiver output when inputs are open or shorted. The MX14784E and MX14787E feature a slew-rate limited driver that minimizes EMI and reduces reflections caused by improperly-terminated cables, allowing errorfree data transmission at data rates up to 5kbps. The MX14784E/MX14787E feature an added deglitch filter on the receiver signal path for enhanced noise immunity when differential signals have very slow rise and fall times. river outputs are short-circuit current-limited, with thermal shutdown circuitry that protects drivers against excessive power dissipation. The MX14784E/MX14786E/ transceivers draw 4m (max) of supply current when unloaded, or when fully-loaded with the drivers disabled. The MX14784E and MX14786E draw less than 1μ (max) of supply current in low-power shutdown mode. True Fail-Safe The MX14784E/MX14786E/ guarantee a logic-high receiver output when either the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. If the differential receiver input voltage (V - V) is greater than or equal to -1mV, is logic-high. eceiver Input eglitch Filter (MX14784E/ MX14787E Only) The MX14784E/MX14787E include integrated circuitry to filter received data. This input deglitch filter reduces false triggers that can occur when data is passed over long cables. To minimize impact on the bus, the integrated filter is not connected to the receiver inputs. Instead, data is filtered after the differential receiver input but before reaching. river Single-Ended Operation The and outputs can either be used in the standard differential operating mode, or can be used a singleended outputs. Since the and driver outputs swing rail-to-rail, they can individually be used as standard TTL logic outputs. Maxim Integrated 13

14 Half-uplex Operation The MX14784E/MX14786E are full-duplex transceivers with driver and receiver enable/disable functionality. To use these devices in a half-duplex configuration, connect the output to the input and connect the output to the input. river Output Protection Two mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention. The first, a current limit on the output stage, provides immediate protection against short-circuits over the whole common-mode voltage range. The second, a thermal shutdown circuit, force the driver outputs into a high-impedance state if the die temperature exceeds +16 C (typ). Low-Power Shutdown Mode (MX14784E/ MX14786E Only) Low-power shutdown mode is initiated by bringing both high and low. In shutdown, the devices draw only 1µ (max) of supply current. and can be driven simultaneously; the devices are guaranteed not to enter shutdown if is high and is low for less than 5ns. If the inputs are in this state for at least 8ns, the devices are guaranteed to enter shutdown. ±35kV ES Protection ES protection structures are incorporated on all pins to protect against electrostatic discharge encountered during handling and assembly. The driver outputs and receiver inputs of the MX14784E/MX14786E/MX14787E/ MX14789E have extra protection against static electricity. The ES structures withstand high ES in all states: normal operation, shutdown, and powered down. fter an ES event, the devices keep working without latchup or damage. ES protection can be tested in various ways. The transmitter outputs and receiver inputs of the MX14784E/ MX14786E/ are characterized for protection to the following limits: ±35kV HM ±18kV using the ir-gap ischarge method specified in IEC ±8kV using the Contact ischarge method specified in the IEC ES Test Conditions ES performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test setup, test methodology, and test results. Human ody Model (HM) Figure 9 shows the HM test model, while Figure 1 shows the current waveform it generates when discharged in a low-impedance state. This model consists of a 1pF capacitor charged to the ES voltage of interest, which is then discharged into the test device through a 1.5kΩ resistor. IEC The IEC standard covers ES testing and performance of finished equipment. However, it does not specifically refer to integrated circuits. The MX14784E/ MX14786E/ help facilitate designing equipment to meet the IEC specification without the need for additional ES protection components. The major difference between tests performed using the HM and IEC is higher peak current in IEC due to lower series resistance in the IEC model. Hence, the ES withstand voltage measured to IEC is generally lower than that measured using the HM. Figure 11 shows the IEC model, while Figure 1 shows the current waveform for IEC ES Contact ischarge Test. Maxim Integrated 14
