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.
