DESCRIPT ION TheHCC4536B(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 consisting of 24 ripple-binary counter stages.Thesalient featureof this device is its flexibility. The devicecan count from 1 to 224or the first 8 stages can be bypassed to allow an output, selectable by a 4-bit code, from any oneof the remaining 16 stages. It can be driven by an external clock or an RC oscillator that canbe constructedusing on-chip components.

InputIN1serves as either theexternal clockinputor the input to the on-chip RC oscillator. OUT1 and OUT2 are connection terminalsfor the external RC components.Inaddition,anon-chipmonostablecircuit is provided to allow a variable pulse widthoutput. Various timing functionscan be achieved using combinations of these capabilities. A logic 1 on the 8-BYPASS input enables a bypass of the first 8 stages and makes stage 9 the firstcounterstageof the last16stages.Selection of1of16 outputsisaccomplished by the decoder andthe BCD inputs A, B, C

and D. MONO IN is the timing input for the on-chip monostable oscillator. Grounding of the MONO IN terminalthrough a resistor of10KΩ or higher, disables the one-shot circuitand connects the decoder directly to the DECODE OUT terminal. A resistorto VDDand a capacitor to ground from the MONO IN terminalenables theone-shot circuitand controls its pulse width. A fast test mode is enabled by a logic 1 on 8-BYPASS, SET, and RESET. This mode divides the 24-stage counter into three 8-stagesections to facilitate a fast test sequence.
