The device is designed to meet TIA/EIA-422-B and ITU Recommendation V.11 drivers with reduced supply voltage. The high current capability of the outputs allow for driving balanced lines, such as twisted-pair transmission lines, and proved a high impedance in the power-off condition. The AM26LV31E is optimized for balanced-bus transmission line at switching rates up to 32 MHz. From a single 3.3-V power supply, the device operates four 3-state differential line drivers with integrated active high and active low enables for precise control. The device is capable of accepting 5-V logic inputs with a 3.3-V supply. The driver is designed to handle loads of a minimum of ±30 mA of sink or source current. 8.2 Functional Block Diagram G G 1A 2A 3A 4A 4 12 2 1 3 6 7 5 10 9 11 15 14 13 1Y 1Z 2Y 2Z 3Y 3Z 4Y 4Z Copyright © 2016, Texas Instruments Incorporated Figure 7.

The transmitter outputs are enabled when either G is set to logic HIGH or G is set to logic LOW. The reverse disables the outputs (G = LOW, G = HIGH). See Table 1 for the complete truth table. 8.3.2 High Output Impedance for Specific Driver Enable Inputs When the AM26LV31E transmitter outputs are disabled using G and G logic inputs, the outputs are set to a high impedance state. 10 Submit Documentation Feedback Copyright © 2008–2016, Texas Instruments Incorporated Product Folder Links: AM26LV31E AM26LV31E www.ti.com SLLS848B – APRIL 2008 – REVISED SEPTEMBER 2016 8.4 Device Functional Modes Table 1 lists the functional modes of the AM26LV31E.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information x x x x x x x x xxxxxxxxxxxxxx x x When designing a system that uses drivers, receivers, and transceivers that comply with RS-422 or RS-485, proper cable termination is essential for highly reliable applications with reduced reflections in the transmission line. Because RS-422 allows only one driver on the bus, if termination is used, it is placed only at the end of the cable near the last receiver. In general, RS-485 requires termination at both ends of the cable. Factors to consider when determining the type of termination usually are performance requirements of the application and the ever-present factor, cost. The different types of termination techniques discussed are unterminated lines, parallel termination, AC termination, and multipoint termination. Laboratory waveforms for each termination technique (except multipoint termination) illustrate the usefulness and robustness of RS-422 (and indirectly, RS485). Similar results can be obtained if 485-compliant devices and termination techniques are used. For laboratory experiments, 100 feet of 100-Ω, 24-AWG, twisted-pair cable (Bertek) was used. A single driver and receiver, TI AM26LV31E and AM26LV32E, respectively, were tested at room temperature with a 3.3-V supply voltage. To show voltage waveforms related to transmission-line reflections, the first plot shows output waveforms from the driver at the start of the cable (A/B); the second plot shows input waveforms to the receiver at the far end of the cable (Y). x x x xx x xx x 9.2 Typical Application Servo Drive Encoder Interpolation Electronics A Motion Controller D R Encoder Phase A D R Encoder Phase B D R Encoder Index D R Status B Z Status AM26LV32E AM26LV31E Copyright © 2016, Texas Instruments Incorporated Figure 10.

If desired, add external fail-safe biasing to ensure 200 mV on the A-B port, if the drive is in high impedance state (see Failsafe in RS-485 data buses, SLYT080). 9.2.3 Application Curve 5 4 Voltage (V) 3 2 1 0 ±1 ±2 Y A/B ±3 0 0.1 0.2 0.3 Time ( s) 0.4 0.5 C001 Figure 11.

Bypass capacitors are used to reduce the coupled noise by providing low impedance power sources local to the analog circuitry. – Connect low-ESR, 0.1-μF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for singlesupply applications. • Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. • To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed to in parallel with the noisy trace. • Place the external components as close to the device as possible. Keeping RF and RG close to the inverting input minimizes parasitic capacitance. • Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitive part of the circuit. 11.2 Layout Example For all Y and Z outputs, make sure the traces are impedance matched to cable used.
