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 2

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.
