mc1489, mc1489a http://onsemi.com 6 applications information general information the electronic industries association (eia) has released the eia232d specification detailing the requirements for the interface between data processing equipment and data communications equipment. this standard specifies not only the number and type of interface leads, but also the voltage levels to be used. the mc1488 quad driver and its companion circuit, the mc1489 quad receiver, provide a complete interface system between dtl or ttl logic levels and the eia232d defined levels. the eia232d requirements as applied to receivers are discussed herein. the required input impedance is defined as between 3000 w and 7000 w for input voltages between 3.0 and 25 v in magnitude; and any voltage on the receiver input in an open circuit condition must be less than 2.0 v in magnitude. the mc1489 circuits meet these requirements with a maximum open circuit voltage of one v be . the receiver shall detect a voltage between 3.0 and 25 v as a logic a1o and inputs between 3.0 and 25 v as a logic a0.o on some interchange leads, an open circuit of power aoffo condition (300 w or more to ground) shall be decoded as an aoffo condition or logic a1.o for this reason, the input hysteresis thresholds of the mc1489 circuits are all above ground. thus an open or grounded input will cause the same output as a negative or logic a1o input. device characteristics the mc1489 interface receivers have internal feedback from the second stage to the input stage providing input hysteresis for noise rejection. the mc1489 input has typical turnon voltage of 1.25 v and turnoff of 1.0 v for a typical hysteresis of 250 mv. the mc1489a has typical turnon of 1.95 v and turnoff of 0.8 v for typically 1.15 v of hysteresis. each receiver section has an external response control node in addition to the input and output pins, thereby allowing the designer to vary the input threshold voltage levels. a resistor can be connected between this node and an external power supply. figures 4, 6 and 7 illustrate the input threshold voltage shift possible through this technique. this response node can also be used for the filtering of high frequency, high energy noise pulses. figures 10 and 11 show typical noise pulse rejection for external capacitors of various sizes. these two operations on the response node can be combined or used individually for many combinations of interfacing applications. the mc1489 circuits are particularly useful for interfacing between mos circuits and mdtl/mttl logic systems. in this application, the input threshold voltages are adjusted (with the appropriate supply and resistor values) to fall in the center of the mos voltage logic levels (see figure 12). the response node may also be used as the receiver input as long as the designer realizes that he may not drive this node with a low impedance source to a voltage greater than one diode above ground or less than one diode below ground. this feature is demonstrated in figure 13 where two receivers are slaved to the same line that must still meet the eia232d impedance requirement. pw, input pulse width (ns) 500 pf mc1489 6 5 4 3 2 1 10,000 1000 100 10 300 pf 100 pf 10 pf e , amplitude (v) in figure 10. typical turn on threshold versus capacitance from response control pin to gnd mc1489a pw, input pulse width (ns) 12 pf 500 pf 100 pf 300 pf 6 5 4 3 2 1 10,000 1000 100 10 e , amplitude (v) in figure 11. typical turn on threshold versus capacitance from response control pin to gnd
