TP1981数据手册3PEAK中文资料规格书

描述 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.
