Figure 11. A Bipolar to CMOS TTL Line Receiver (N, Q
Package Pinout)
Bipolar to CMOS/TTL
It is sometimes desirable to translate a bipolar signal (e.g.,
±5 V) coming from a communications cable or another section
of the system to CMOS/TTL logic levels; such an application is
referred to as a line receiver. Previously, the interface to the
bipolar signal required either a dual (
±) power supply or a refer-
ence voltage level about which the line receiver would switch.
The AD790 may be used in a simple circuit to provide a unique
capability: the ability to receive a bipolar signal while powered
from a single 5 V supply. Other comparators cannot perform
this task. Figure 11 shows a 1 k
resistor in series with the input
signal which is then clamped by a Schottky diode, holding the
input of the comparator at 0.4 V below ground. Although the
comparator is specified for a common mode range down to –VS,
(in this case ground) it is permissible to bring one of the inputs
a few hundred mV below ground. The comparator switches
around this level and produces a CMOS/TTL compatible swing.
The circuit will operate to switching frequencies of 20 MHz.
