DESCRIPTION
The HCC4536B (extended temperature range) and
HCF4536B (intermediate temperature range) are
monolithic integrated circuits, available in 16-lead
dual in-line plastic or ceramic package. The
HCC/HCF4536B is a programmable timer consi-
sting of 24 ripple-binary counter stages. The salient
feature of this device is its flexibility. The device can
count from 1 to 224 or the first 8 stages can be by-
passed to allow an output, selectable by a 4-bit co-
de, from any one of the remaining 16 stages. It can
be driven by an external clock or an RC oscillator
that can be constructed using on-chip components.
