description
The TLC193 and TLC393 consist of dual
independent micropower voltage comparators
designed to operate from a single supply. They
are functionally similar to the LM393 but uses
one-twentieth the power for similar response
times. The open-drain MOS output stage
interfaces to a variety of loads and supplies. For

PARAMETER MEASUREMENT INFORMATION
The TLC393 contains a digital output stage which, if held in the linear region of the transfer curve, can cause
damage to the device. Conventional operational amplifier/comparator testing incorporates the use of a servo
loop that is designed to force the device output to a level within this linear region. Since the servo-loop method
of testing cannot be used, the following alternatives for testing parameters such as input offset voltage,
common-mode rejection ratio, etc., are suggested.
Toverifythattheinputoffsetvoltagefallswithinthelimitsspecified, thelimitvalueisappliedtotheinputasshown
in Figure 1(a). With the noninverting input positive with respect to the inverting input, the output should be high.
With the input polarity reversed, the output should be low.
A similar test can be made to verify the input offset voltage at the common-mode extremes. The supply voltages
can be slewed as shown in Figure 1(b) for the V
greater accuracy.

PARAMETER MEASUREMENT INFORMATION
A close approximation of the input offset voltage can be obtained by using a binary search method to vary the
differential input voltage while monitoring the output state. When the applied input voltage differential is equal,
but opposite in polarity, to the input offset voltage, the output changes states.
Figure 2 illustrates a practical circuit for direct dc measurement of input offset voltage that does not bias the
comparator in the linear region. The circuit consists of a switching-mode servo loop in which U1A generates
a triangular waveform of approximately 20-mV amplitude. U1B acts as a buffer, with C2 and R4 removing any
residual dc offset. The signal is then applied to the inverting input of the comparator under test, while the
noninverting input is driven by the output of the integrator formed by U1C through the voltage divider formed
by R9 and R10. The loop reaches a stable operating point when the output of the comparator under test has
a duty cycle of exactly 50%, which can only occur when the incoming triangle wave is sliced symmetrically or
when the voltage at the noninverting input exactly equals the input offset voltage.
The voltage divider formed by R9 and R10 provides an increase in input offset voltage by a factor of 100 to
make measurement easier. The values of R5, R8, R9, and R10 can significantly influence the accuracy of the
reading; therefore, it is suggested that their tolerance level be 1% or lower.
Measuring the extremely low values of input current requires isolation from all other sources of leakage current
and compensation for the leakage of the test socket and board. With a good picoammeter, the socket and board
leakage can be measured with no device in the socket. Subsequently, this open-socket leakage value can be
subtracted from the measurement obtained with a device in the socket to obtain the actual input current of the
device.

PARAMETER MEASUREMENT INFORMATION
Propagationdelaytimeisdefinedastheintervalbetweentheapplicationofaninputstepfunctionandtheinstant
when the output reaches 50% of its maximum value. Propagation delay time, low-to-high-level output, is
measured from the leading edge of the input pulse, while propagation delay time, high-to-low-level output, is
measured from the trailing edge of the input pulse. Propagation delay time measurement at low input signal
levels can be greatly affected by the input offset voltage. The offset voltage should be balanced by the
adjustment at the inverting input (as shown in Figure 3) so that the circuit is just at the transition point. Then a
low signal, for example, 105 mV or 5 mV overdrive, causes the output to change state.

APPLICATION INFORMATION
The input should always remain within the supply rails in order to avoid forward biasing the diodes in the electrostatic
discharge (ESD) protection structure. If either input exceeds this range, the device will not be damaged as long as
the input current is limited to less than 5 mA. To maintain the expected output state, the inputs must remain within
the common-mode range. For example, at 25°C with V
to assure proper device operation.
= 5 V, both inputs must remain between –0.2 V and 4 V
DD
To assure reliable operation, the supply should be decoupled with a capacitor (0.1-µF) positioned as close to the
device as possible.
The TLC393 has internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested
under MIL-STD-883C, Method 3015.2; however, care should be exercised in handling these devices, as exposure
to ESD may result in the degradation of the device parametric performance.
