They are not meant to imply that the devices should be operated at these limits. The table of Electrical Characteristics specifies conditions of device operation. Note 2: Current into device pins is defined as positive. Current out of the device pins is defined as negative. All voltages are referenced to ground unless otherwise specified. For current, minimum and maximum values are specified as an absolute value and the sign is used to indicate direction. For voltage logic levels, the more positive value is designated as maximum. For example, if −6V is a maximum, the typical value −6.8V is more negative. Note 3: All typicals are given for: VCC = +3.3V, V+ = +12V, V− = −12V, TA = +25˚C. Note 4: Only one driver output shorted at a time. Note 5: Generator characteristics for driver input: f = 64 kHz (128 kbps), tr = tf < 10 ns, VIH = 3V, VIL = 0V, duty cycle = 50%. Note 6: Generator characteristics for receiver input: f = 64 kHz (128 kbps), tr = tf = 200 ns, VIH = 3V, VIL = −3V, duty cycle = 50%. Note 7: If receiver inputs are unconnected, receiver output is a logic high. Note 8: Refer to typical curves. Driver output slew rate is measured from the +3V to the −3V level on the output waveform. Inputs not under test are connected to VCC or GND. Slew rate is determined by load capacitance. To comply with a 30 V/µs maximum slew rate, a minimum load capacitance of 390 pF for DSV14196 or 620 pF for DSV14196T is recommended. 5 www.national.com Parameter Measurement Information DS100853-3 FIGURE 1.

The data lines are TXD and RXD. The control lines are RTS, DTR, DSR, DCD, CTS and RI. The DSV14196/DSV14196T is a 5 x 3 Driver/Receiver and offers a single chip solution for this DTE interface. As shown in Figure 5, this interface allows for direct flow-thru interconnect. For a more conservative design, the user may wish to insert ground traces between the signal lines to minimize cross talk. MOUSE DRIVING A typical mouse can be powered from the drivers. Two driver outputs connected in parallel and set to VOH can be used to supply power to the V+ pin of the mouse. The third driver output is set to VOL to sink the current from the V−terminal. Refer to typical curves of VOUT/IOUT.Typical mouse specifications are: 10 mA at +6V 5 mA at −6V FAILSAFE RECEIVER OUTPUTS The DSV14196/DSV14196T features failsafe receiver outputs. In failsafe mode, if the receiver input becomes zero or an open-circuit, the receiver output is pulled to a high level. DS100853-7 FIGURE 5.
