High-Speed 18V CMOS Comparators
Features
ISL55141, ISL55142, ISL55143 integrated circuits are
high-speed, wide input common-mode range comparators.
They provide three-state window comparators in a high
voltage CMOS process (18V). Each comparator has dual
receive thresholds, CVA and CVB, for establishing
minimum 1-VIH and maximum 0-VIL voltage levels. These
devices can accept inputs from a number of logic families,
such as TTL, ECL, CMOS, LVCMOS, LVDS and CML. Two
bits of output per comparator provide the test controller with
qualification of a comparator input into three states. The two
output bits work with a separate user supply to establish
VOH, VOL levels compatibility with the system’s controller
logic levels.
• 18V I/O Range
Fast propagation delay (9.5ns typical at ±50mV overdrive)
makes this family compatible with high-speed digital test
systems. The 18V range enables the comparator input to
operate over a wide input range. Two references per input
enable and three state digitalization of input with voltage
swings of up to 13V common mode. The operating
frequency of these devices is typically 65MHz.
Applications
FN6230.4
• 65MHz Operation
• 9.5ns Typical Propagation Delay

NOTES:
9. Lab characterization, room temperature, timing parameters matched stimulus/loads, channel-to-channel skew < 500ps, 1ns maximum by design
10. Note about ICC measurement input can approach 140mA (single comparator) at maximum pattern rates
11. Limits should be considered typical and are not production tested.
12. Total Power dissipation per comparator can be approximately calculated from the following:
P = (VCC-VEE)*8.25mW + 90pF*(VCC-VEE)^2*f + CL*(VCC-VEE)^2*f, where f is the operating frequency and CL is the load capacitance.
Because the ISL55142 has two comparators, the power dissipation would be twice of P calculated from this equation. The ISL55143 would be
four times P.
13. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

Although there is no electrical difference between the CVA
and CVB Inputs, if one defines CVA as being the high
threshold and CVB being the low threshold, it becomes
easier to understand the utilization of a dual threshold
comparator. Essentially this enables the qualification of an
incoming signal into three states. In Figure 3, the three
states are Valid Low <0.4V, No-man’s-land (between 0.4
and 2.4V), Valid High >2.4V. Table 2 shows how the QA/QB

Application Information
The ISL55141, ISL55142, ISL55143 provide 1, 2 and 4 dual
threshold, three-state window comparator(s) in TSSOP or
QFN footprints. They offer a combination of speed (10ns Tpd
and wide voltage range (18V). This product directly
addresses the need for unique common-mode
characteristics while supplying a power-down feature.
Figures 4 and 5 show the stimulus setup and measurement
points for an example propagation delay measurement.
Typical room temperature results are displayed in Figure 12.
FIGURE 5. tPD RECEIVER PROPAGATION DELAY
MEASUREMENT POINTS
The truth table for the receivers is given in Table 1. Receiver
outputs are not tri-statable, and do not incorporate any on-chip
short circuit current protection. Momentary short circuits to
GND, or any supply voltage, will not cause permanent
damage, but care must be taken to avoid longer duration short
circuits. If tolerable to the application, current limiting resistors
can be inserted in series with the QAX and QBX outputs to
protect the receiver outputs from damage due to overcurrent
conditions.
Power-down Features
Figure 5 shows a VINP range of 50mV. In Figure 12 the
offset is increased in the horizontal axis from 50mV above
and below the reference (1.5V) up to 2.5V above and below
the 1.5V reference.
The ISL55141, ISL55142, ISL55143 PD pin provides a
means of reducing current consumption when the device is
not in use. Supply currents fall from ~7mA to less than 10µA
in the power-down mode. The device requires approximately
10µs to power-down and 15µs to power-up.
Two lines are displayed in Figure 12. One represents the
rising-to-rising delay (tPDLH) and the other the
falling-to-falling delay (tPDHL).
Power Supply Bypassing and Printed Circuit
Board Layout
Comparator Features
These three-state window comparators feature high output
current capability, and user defined high and low output levels
to interface with a wide variety of logic families. Each receiver
comprises two comparators and each comparator has an
independent threshold level input, making it easy to
implement (Minimum1-VIH)/(Maximum 0-VIL) logic level
comparator functions. The CVAX and CVBX pins set the
threshold levels of the A and B comparators respectively. VOH
and VOL set all the comparator output levels, and VOH must
be more positive than VOL. These two inputs are unbuffered
supply pins, so the sources driving these pins must provide
adequate current for the expected load. VOH and VOL
typically connect to the power supplies of the logic device
driven by the comparator outputs.
6
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended, lead lengths
should be as short as possible, and the power supply pins
must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, where the VEE pin is
connected to ground, one 0.1µF ceramic capacitor should be
placed from the VCC pin to ground. A 4.7µF tantalum
capacitor should then be connected from the VCC pin to
ground. This same capacitor combination should be placed
at each supply pin to ground if split supplies are to be used.
Power Dissipation Considerations
Specifying continuous data rates, driver loads and driver
level amplitudes are key in determining power supply
requirements as well as dissipation/cooling necessities.
Driver output patterns also impact these needs. The faster
the pin activity, the greater the need to supply current and
remove heat.

OPTIONAL PROTECTION
DIODE
The power dissipation calculated from the above formula
may have an error of ±20 to 25%.
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the loads.
Power also depends on the number of channels changing
state and frequency of operation. The extent of continuous
active pattern generation/reception will greatly affect
dissipation requirements.
The user should evaluate various heat sink/cooling options
in order to control the ambient temperature part of the
equation. This is especially true if the user’s applications
require continuous, high-speed operation.
Note: The reader is cautioned against assuming the same
level of thermal performance in actual applications. A careful
inspection of conditions in your application should be
conducted.
7
Circuit design must always take into account the internal
EOS/ESD protection structure of the device.
Important Note: The QFN package metal plane is used for
heat sinking of the device. It is electrically connected to the
negative supply potential (VEE). If VEE is tied to ground, the
thermal pad can be connected to ground. Otherwise, the
thermal pad (VEE) must be isolated from other power
planes.
Power Supply Sequencing
The ISL55141, ISL55142, ISL55143 reference every supply
with respect to VEE. Therefore, apply VEE, VOL then VCC
followed by the CVA and CVB supplies. The comparator
VINP pin should not exceed VEE or VCC during power-up.
In cases where inputs may exceed voltage rails during
power-up, series resistance should be employed to
safeguard EOS to the ESD protection diodes.
