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
24
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.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
* All voltages are with respect to V
SS
(GND).
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 cir-
cuit is provided to allow a variable pulse width out-
put. 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 sta-
ges and makes stage 9 the first counter stage of the
last 16 stages. Selection of 1 of 16 outputs is accom-
plished 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 10K
or higher, disa-
bles the one-shot circuit and connects the decoder
directly to the DECODE OUT terminal. A resistor to
V
DD
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 di-
vides the 24-stage counter into three 8-stage sec-
tions 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 "1". The counter is now returned to the normal
24-steps in series configuration. One more pulse is
entered into In
1
which will cause the counter to ripple
from an all "1" state to an all "0" state.
