Dual Line Receivers
Each of these devices consists of a dual single-ended line receiver with TTL-compatible strobes and
outputs. The reference voltage (switching threshold) is applied externally and can be adjusted from
1.5 volts to 3.5 volts, making it possible to optimize noise immunity for a given system design. A 2.5-
volt internal reference is available for use on the ‘142A and ‘143A. Due to their low input current (less
than 100 microamperes), they are ideally suited for party-line (bus-organized) systems.
The ‘140 has a common reference voltage pin and a common strobe. The ‘141 is the same as the
‘140 except that the input stage is diode protected. Each receiver of the ‘142A has an individual
reference voltage pin and an individual strobe. The ‘143A is the same as the ‘142A except that
the input stage is diode protected. The internal reference voltage of the ‘142A and ‘143A can be
externally adjusted with a single resistor from 1.5 volts to 3.5 volts.
