Frequency counter up to 1MHZ


Posted on May 27, 2012

The MK50398 is one modern decimal counter up/down of six tens, with control of screen LED of seven segments and flip-flop of storage. Counter it can measure additive and abstractively. The IC MK50398 is ideal for manufacture frequency counter as the particular circuit. The frequency of measurement is from 0 HZ until roughly 1MHZ.
