Description
The 3PEAK INCORPORATED TP194x families of
CMOS/TTL compatible comparators are offered in
single, dual, and quad configurations, and are
exceptionally versatile and easy to use.
The TP194x incorporate 3PEAK’s proprietary and
patented design techniques to achieve the ultimate
combination of high-speed (68ns propagation delay
under 1.8~5.5V wide supply range) and low power
consuming (46μA quiescent current per comparator).
These comparators are optimized for low power
1.8V, single-supply applications with greater than
rail-to-rail input operation, and also operate with
±0.9V to ±2.75V dual supplies. The input common
mode voltage range extends 200mV below ground
and 200mV above supply, allowing both ground and
supply sensing. 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 4 MHz while limiting
supply current surges and dynamic power
consumption during switching.
The TP1941 single comparators are available in
shout-down function, output latch version, and the
tiny SC70/SOT23 package for space-conservative
designs. All devices are specified for the
temperature range of –40°C to +85°C.

Input Current: +IN, –IN, Note 2..........................±10mA
Output Current: OUT.................................... ±45mA
Output Short-Circuit Duration Note 3…......... Indefinite
Operating Temperature Range.........–40°C to 85°C
Maximum Junction Temperature................... 150°C
Storage Temperature Range.......... –65°C to 150°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.
