MAX9202EUD-MAX9203ESA
Low-Cost, 7ns, Low-Power Voltage Comparators
General DescriptionThe MAX9201/MAX9202/MAX9203 high-speed, low-
power, quad/dual/single comparators feature TTL logic
outputs with active internal pullups. Fast propagation
delay (7ns typ at 5mV overdrive) makes these devices
ideal for fast A/D converters and sampling circuits, line
receivers, V/F converters, and many other data-discrim-
ination, signal restoration applications.
All comparators can be powered from separate analog
and digital power supplies or from a single combined
supply voltage. The analog input common-mode range
includes the negative rail, allowing ground sensing
when powered from a single supply. The MAX9201/
MAX9202/MAX9203 consume only 9mW per compara-
tor when powered from a +5V supply.
The MAX9202/MAX9203 feature output latches with TTL
compatible inputs. The comparator output states are
held when the latch inputs are driven low. The
MAX9201 provides all the same features as the
MAX9202/MAX9203 with the exception of the latches.
The MAX9201/MAX9202/MAX9203 are lower power and
lower cost upgrades to the MAX901/MAX902/MAX903
offering a 50% power savings and smaller packaging.

Applications Information
Circuit LayoutBecause of the large gain-bandwidth transfer function
of the MAX9201/MAX9202/MAX9203 special precau-
tions must be taken to realize their full high-speed
capability. A printed circuit board with a good, low-
inductance ground plane is mandatory. All decoupling
capacitors (the small 100nF ceramic type is a good
choice) should be mounted as close as possible to the
power-supply pins. Separate decoupling capacitors for
analog VCCand for digital VDDare also recommended.
Close attention should be paid to the bandwidth of the
decoupling and terminating components. Short lead
lengths on the inputs and outputs are essential to avoid
unwanted parasitic feedback around the comparators.
Solder the device directly to the printed circuit board
instead of using a socket.
Input Slew-Rate RequirementsAs with all high-speed comparators, the high gain-band-
width product of the MAX9201/MAX9202/ MAX9203 can
create oscillation problems when the input traverses the
linear region. For clean output switching without oscilla-
tion or steps in the output waveform, the input must meet
minimum slew-rate requirements (0.5V/s typ). Oscillation
is largely a function of board layout and of coupled
source impedance and stray input capacitance. Both
poor layout and large source impedance will cause the
part to oscillate and increase the minimum slew-rate
requirement. In some applications, it may be helpful to
apply some positive feedback between the output and
positive input. This pushes the output through the transi-
tion region clearly, but applies a hysteresis in threshold
seen at the input terminals.
TTL Output and Latch InputsThe comparator TTL output stages are optimized for
driving low-power Schottky TTL with a fan-out of four.
When the latch is connected to a logic high level, the
comparator is transparent and immediately responds to
changes at the input terminals. When the latch is con-
nected to a TTL low level, the comparator output latch-
es (in the same state) the instant that the latch
command is applied, and will not respond to subse-
quent changes at the input. No latch is provided on
the MAX9201.
