TP1981

概述

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 with 4 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.
