Datasheet
1.0 General description.
HTC555 is a general-purpose clock generator. It requires no
external components and provides wide range of clock
frequencies. It’s very easy to use and provides general clock
solution in wide range of applications. It is very simple to design
and operate. Output frequency is determined by value of D[0:4].
Refer to Output frequency table.

... With this application we can generate thirty-two different output frequencies. See output frequency selection table for dip switch settings. Setting “Frequency Selection” dip switch sets frequency. HTC555 reads input switch value constantly and output frequency is set per new value if D[0:4] inputs are changed. Time that takes to change output frequency to new value is relative to period of previous frequency setting ...
