Description
The TP1981 is a very fast comparator. These comparators
are exceptionally versatile and easy to use. Features include
an input common mode range from -0.2 V to VCC-1.5 V, low
noise, TTL-/CMOS-compatible output drivers, and shutdown
inputs.
The device offers 3.5 ns propagation delay with 100 mV
overdrive with4 mA typical quiescent current. The maximum
detectable signal frequency exceeds 250MHz.
The TTL-/CMOS-compatible output stage is designed to
drive up to 10 pF with full timing specs and to degrade in a
graceful and linear fashion as additional capacitance is
added. The comparator input stage offers robust protection
against large input overdrive, and the output does not
phase-reverse when the valid input signal range is exceeded.
The TP1981 is available in a 6-lead SC70 package.

* 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.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the
supply rails should be current limited to 10mA or less.
