Features include three–state outputs, thermal shutdown, and output current limiting in both directions. These devices also comply with EIA–422–A, and CCITT Recommendations V.11 and X.27. The MC75172B/174B are optimized for balanced multipoint bus transmission at rates in excess of 10 MBPS. The outputs feature wide common mode voltage range, making them suitable for party line applications in noisy environments. The current limit and thermal shutdown features protect the devices from line fault conditions. These devices offer optimum performance when used with the MC75173 and MC75175 line receivers. Both devices are available in 16–pin plastic DIP and 20–pin wide body surface mount packages.

Description

The MC75172B and MC75174B are differential line drivers designed to comply with EIA–485 Standard (April 1983) for use in balanced digital multipoint systems containing multiple drivers. The drivers also comply with EIA–422–A and CCITT Recommendations V.11 and X.27. The drivers meet the EIA–485 requirement for protection from damage in the event that two or more drivers attempt to transmit data simultaneoulsy on the same cable. Data rates in excess of 10 MBPS are possible, depending on the cable length and cable characteristics. A single power supply, 5.0 V, ±5%, is required at a nominal current of 60 mA, plus load currents. Outputs Each output (when active) will be a low or a high voltage, which depends on the input state and the load current (see Table 1, 2 and Figures 7 to 10). The graphs apply to each driver, regardless of how many other drivers within the package are supplying load current. Table 1. MC75172B Truth Table Table 2. MC75174B Truth Table voltage between –7.0 V and 12 V without damage. resetting upon removal of the fault condition. design practices dictate that inputs should never be left open.

1. This graph is not affected by the state of the Enable pins.

(Pins 4 and 12) are true according to Tables 1 and 2. characteristics are shown in Figure 15. EIA–422–A is the reason for the narrower temperature range.

Figure 18. Typical EIA–485 System NOTES: 1. Terminating resistors RT must be located at the physical ends of the cable.

1. Stubs should be as short as possible.
2. Circuit ground of all drivers and receivers must be connected via a dedicated wire within the cable.

Do not rely on chassis ground or power line ground. R T = 120 Ω at each end of the cable.
