The TP1961/TP1962/TP1964 are low-power,
ultra-high-speed comparators with internal
hysteresis. These devices are optimized for single
+3V or +5V operation. The input common-mode
range extends 300mV beyond the rail, and the
outputs can sink or source 4mA to within 80mV of
GND and VCC. Propagation delay is 7ns (50mV
overdrive), while supply current is 1mA per
comparator.
The internal input hysteresis eliminates output
switching due to internal input noise voltage,
reducing current draw. The push-pull output
supports rail-to-rail output swing, and interfaces with
CMOS/TTL logic. The output toggle frequency can
reach a typical of 50 MHz while limiting supply
current surges and dynamic power consumption
during switching.
The TP1961 single comparators are available in
shout-down function, and the tiny SOT23 package
for space-conservative designs. All devices are
specified for the temperature range of –40°C to
+85°C.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any
Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power
supply, the input current should be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage
and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified
values are for short traces connected to the leads.

trip points.
Note 2: Propagation Delay Skew is defined as: tPD-SKEW = tPD+ - tPD-.
