... Logic lines are shared between the two protocols and are used for signal inputs and as an RS-485 driver enable. The MAX3162 is a 2Tx/2Rx RS-232 transceiver and a single RS-485/422 transceiver simultaneously. All dri- vers, receivers, and transmitters can be enabled or dis- abled by pin configuration. All outputs are high-Z when not activated. RS-232 receiver inputs are 5kΩ ...

... MAX3162 permit their receiver inputs to be driven to ±25V. Floating receiver input signals are pulled to ground through internal 5kΩ resistors, forcing the out- puts to a logic high. The MAX3162 has transmitter and receiver enable pins that allow its outputs to be three- stated. ...

... The MAX3160/MAX3161/MAX3162 maintain the RS-232 ±5.0V required minimum transmitter output voltage even at high data rates. Figure 11 shows a transmitter loop- back test circuit. Figure 12 shows a loopback test result at 250kbps, and Figure 13 shows the same test at 1000kbps. Figure 12 demonstrates a single slew-rate limited transmitter driven at 250kbps (FAST = GND) into an RS-232 load in parallel with 1000pF ...

... This impedance may be reduced if the D1 pin is toggled at a high fre- quency. With no power applied (V 485 transmitter output impedances typically go to 1/2- unit load on the MAX3161/MAX3162, and to one-unit load on the MAX3160. Driver Output Protection Two mechanisms prevent excessive output current and power dissipation caused by faults or by bus con- tention ...

... For line lengths greater than 4000 feet, use the repeater application shown in Figure 14. RS-232/RS-485 Protocol Translator Figure 15 shows the MAX3162 configured as an RS- 232/RS-485 protocol translator. The direction of transla- tion is controlled through the RTS signal (R1IN). The single-ended RS-232 receiver input signal is translated to a differential RS-485 transmitter output ...
