APPLICATION INFORMATION
SN75108A dot-AND output connections
The SN75108A line receiver features an open-collector-output circuit that can be connected in the dot-AND
logic configuration with other similar open-collector outputs. This allows a level of logic to be implemented
without additional logic delay.
Output

increasing common-mode input voltage range of receiver
The common-mode voltage range (CMVR) is defined as the range of voltage applied simultaneously to both
input terminals that, if exceeded, does not allow normal operation of the receiver.
The recommended operating CMVR is
±3 V, making it useful in all but the noisiest environments. In extremely
noisy environments, common-mode voltage can easily reach
±10 V to ±15 V if some precautions are not taken
to reduce ground and power supply noise, as well as crosstalk problems. When the receiver must operate in
such conditions, input attenuators should be used to decrease the system common-mode noise to a tolerable
level at the receiver inputs. Differential noise is also reduced by the same ratio. These attenuators were omitted
intentionally from the receiver input terminals so the designer can select resistors that are compatible with his
particular application or environment. Furthermore, the use of attenuators adversely affects the input sensitivity,
the propagation delay time, the power dissipation, and in some cases (depending on the selected resistor
values) the input impedance; thereby reducing the versatility of the receiver.
The ability of the receiver to operate with approximately
±15 V common-mode voltage at the inputs has been
checked using the circuit shown in Figure 15. Resistors R1 and R2 provide a voltage-divider network. Dividers
with three different values presenting a 5-to-1 attenuation were used to operate the differential inputs at
approximately
±3 V common-mode voltage. Careful matching of the two attenuators is needed to balance the
overdrive at the input stage. The resistors used are shown in Table 1.

Attenuator 1:
R1 = 2 k

R2 = 0.5 k
Attenuator 2:
R1 = 6 k

R2 = 1.5 k
Attenuator 3:
R1 = 12 k
,
R2 = 3 k
