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.

HCC/HCF4536B
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
FUN CTIONAL DI AG R A M
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.
