APPLICATIONS INFORMATION
General Information
The Electronic Industries Association (EIA) has releasedthe EIA−232D specification detailing the requirements forthe interface between data processing equipment and datacommunications equipment. This standard specifies notonly the number and type of interface leads, but also thevoltage levels to be used. The MC1488 quad driver and itscompanion circuit, the MC1489 quad receiver, provide acomplete interface system between DTL or TTL logic levelsand the EIA−232D defined levels. The EIA−232Drequirements as applied to receivers are discussed herein.The required input impedance is defined as between3000W and 7000W for input voltages between 3.0 and 25 Vin magnitude; and any voltage on the receiver input in anopen circuit condition must be less than 2.0 V in magnitude.The MC1489 circuits meet these requirements with amaximum open circuit voltage of one VBE.
The receiver shall detect a voltage between − 3.0 and−25 V as a Logic “1” and inputs between 3.0 and 25 V as aLogic “0.” On some interchange leads, an open circuit ofpower “OFF” condition (300 W or more to ground) shall bedecoded as an “OFF” condition or Logic “1.” For thisreason, the input hysteresis thresholds of the MC1489circuits are all above ground. Thus an open or groundedinput will cause the same output as a negative or Logic “1”input.
Device Characteristics
The MC1489 interface receivers have internal feedbackfrom the second stage to the input stage providing inputhysteresis for noise rejection. The MC1489 input has typical
turn−on voltage of 1.25 V and turn−off of 1.0 V for a typicalhysteresis of 250 mV. The MC1489A has typical turn−on of1.95 V and turn−off of 0.8 V for typically 1.15 V ofhysteresis.
Each receiver section has an external response controlnode in addition to the input and output pins, therebyallowing the designer to vary the input threshold voltagelevels. A resistor can be connected between this node and anexternal power supply. Figures 4, 6 and 7 illustrate the inputthreshold voltage shift possible through this technique.This response node can also be used for the filtering ofhigh frequency, high energy noise pulses. Figures 10 and 11show typical noise pulse rejection for external capacitors ofvarious sizes.
These two operations on the response node can becombined or used individually for many combinations ofinterfacing applications. The MC1489 circuits areparticularly useful for interfacing between MOS circuits andMDTL/MTTL logic systems. In this application, the inputthreshold voltages are adjusted (with the appropriate supplyand resistor values) to fall in the center of the MOS voltagelogic levels (see Figure 12).
The response node may also be used as the receiver inputas long as the designer realizes that he may not drive thisnode with a low impedance source to a voltage greater thanone diode above ground or less than one diode belowground. This feature is demonstrated in Figure 13 where tworeceivers are slaved to the same line that must still meet theEIA−232D impedance requirement.
