DESCRIPTIONHCF4536B 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.
