Logic Level Translators
The HA-4900 series comparators can be used as versatile
logic interface devices as shown in the circuits above.
Negative logic devices may also be interfaced with
appropriate supply connections. If separate supplies are
used for V- and V
LOGIC
-, these logic level translators will
tolerate several volts of ground line differential noise.
RS-232 To CMOS Line Receiver
This RS-232 type line receiver to drive CMOS logic uses a
Schmitt trigger feedback network to give about 1V input
hysteresis for added noise immunity. A possible problem in
an interface which connects two equipments, each plugged
into a different AC receptacle, is that the power line voltage
may appear at the receiver input when the interface
connection is made or broken. The two diodes and a 3W
input resistor will protect the inputs under these conditions.
Window Detector
The high switching speed, low offset current and low offset
voltage of the HA-4900 series makes this window detector
circuit extremely well suited to applications requiring fast,
accurate, decision-making. The circuit above is ideal for
industrial process system feedback controllers or “out-of-
limit” alarm indicators.

Oscillator/Clock Generator
This self-starting fixed frequency oscillator circuit gives
excellent frequency stability. R
1
and C
1
comprise the
frequency determining network while R
2
provides the
regenerative feedback. Diode D
1
enhances the stability by
compensating for the difference between V
OH
and
V
SUPPLY
. In applications where a precision clock generator
up to 100kHz is required, such as in automatic test
equipment, C
1
may be replaced by a crystal.
Schmitt Trigger
(Zero Crossing Detector With Hysteresis)
This circuit has a 100mV hysteresis which can be used in
applications where very fast transition times are required at
the output even though the signal input is very slow. The
hysteresis loop also reduces false triggering due to noise on
the input. The waveforms below show the trip points
developed by the hysteresis loop.
