The TLV2354 consists of four independent,
low-power comparators specifically designed for
single power-supply applications and operateS
with power-supply rails as low as 2 V. When
powered from a 3-V supply, the typical supply
current is only 240 µA.

The TLV2354 is designed using the Texas Instruments LinCMOS technology and, therefore, features an
extremely high input impedance (typically greater than 1012 Ω), which allows direct interfacing with
high-impedance sources. The outputs are N-channel open-drain configurations that require an external pullup
resistor to provide a positive output voltage swing, and they can be connected to achieve positive-logic
wired-AND relationships. The TLV2354I is fully characterized for operation from – 40°C to 85°C. The TLV2354M
is fully characterized for operation from – 55°C to 125°C.
The TLV2354 has internal electrostatic-discharge (ESD)-protection circuits and has been classified with a
1000-V ESD rating using human body model testing. However, care should be exercised in handling this device
as exposure to ESD may result in degradation of the device parametric performance.

† The D package is available taped and reeled. Add the suffix R to the device type (e.g., TLV2352IDR).
‡ The PW packages are only available left-ended taped and reeled (e.g., TLV2354IPW).
These devices have limited built-in protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to network ground.
2. Differential voltages are at the noninverting input terminal with respect to the inverting input terminal.
3. Short circuits from outputs to VDD can cause excessive heating and eventual device destruction.

PARAMETER MEASUREMENT INFORMATION
The digital output stage of the TLV2354 can be damaged if it is held in the linear region of the transfer curve.
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 measuring parameters such as input offset voltage, common-mode rejection, etc., are
offered.
To verify that the input offset voltage falls within the limits specified, the limit value is applied to the input as shown
in Figure 9(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 9(b) for the VICR test rather than changing the input voltages to provide greater
accuracy.

Figure 9. Method for Verifying That Input Offset Voltage Is Within Specified Limits
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.

LinCMOS QUADRUPLE LOW-VOLTAGE DIFFERENTIAL COMPARATORS
SLCS012C – MAY 1992 – REVISED AUGUST 2000
PARAMETER MEASUREMENT INFORMATION
Figure 10 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.
Voltage dividers R9 and R10 provide a step up of the 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
Propagation delay time is defined as the interval between the application of an input step function and the instant when
the output crosses VO = 1 V with VDD = 3 V or when the output crosses VO = 1.4 V with VDD = 5 V. 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 11) so that the circuit is just at the transition point. Then
a low signal, for example a 105-mV or 5-mV overdrive, causes the output to change state.
