DESCRIPTION
HCF4536B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP package.
HCF4536B is a programmable timer consisting 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
bypassed to allow an output, selectable by a 4-bit
code, 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. Input IN1 serves as either the
external clock input or the input to the on-chip RC
oscillator. OUT1 and OUT2 are connection
terminals for the external RC components. In
addition, an on-chip monostable circuit is provided
to allow a variable pulse width output. Various
timing functions can 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 first counter stage
of the last 16 stages. Selection of 1 of 16 outputs
is accomplished by the decoder and the BCD
inputs A, B, C, and D. MONO IN is the timing input

for the on-chip monostable oscillator. Grounding
of the MONO IN terminal through a resistor of 10
KΩ or higher, disables the one shot circuit and
connects the decoder directly to the DECODE
OUT terminal. A resistor to VDD and a capacitor to
ground from the MONO IN terminal enables the
one-shot circuit and 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-stage sections to facilitate a
fast test sequence.

FUNCTIONAL TEST SEQUENCE
Test function has been included for the reduction
of test time required to exercise all 24 counter
stages.This test function divides the counter into
three 8-stage section and 255 counts are loaded in
each of the 8-stage sections in parallel. All
flip-flops are now at a "H". The counter is now
returned to the normal 24-steps in series
configuration. One more pulse is entered into In1
which will cause the counter to ripple from an all
"H" state to an all "L" state.
