DESCRIPTION
The HCC4029B (extended temperature range) and
HCF4029B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in-line plastic or ceramic package and plastic
micro package. The HCC/HCF4029B consists of a
four-stage binary or BCD-decade up/down counter
with provisions for look-ahead carry in both counting
modes. The inputs consist of a single CLOCK,
CARRY-IN (CLOCK ENABLE), BINARY/DECADE,
UP/DOWN, PRESET ENABLE, and four individual
JAM signals. Q1, Q2, Q3, Q4 and a CARRY OUT
signal are provided as outputs. A high PRESET EN-
ABLE signal allows information on the JAM INPUTS
to preset the counter to any state asynchronously
with the clock. A low on each JAM line, when the
PRESET-ENABLE signal is high, resets the counter
to its zero count. The counter is advanced one count
at the positive transition of the clock when the
CARRY-IN and PRESET ENABLE signals, are low.
Advancement is inhibited when the CARRY-IN or
PRESET ENABLE signals are high. The CARRY-
OUT signal is normally high and goes low when the

HCC/HCF4029B
counter reaches its maximum count in the UP mode
or the minimum count in the DOWN mode provided
the CARRY-IN signal is low. The CARRY-IN signal
in the low state can thus be considered a CLOCK
ENABLE. The CARRY-IN terminal must be con-
nected to VSS whennot in use. Binary counting is ac-
complished when the BINARY/DECADE input is
high ; the counter counts in the decade mode when
the BINARY/DECADE input is low. The counter
counts Up when to UP/DOWN INPUT is high, and
Down when the UP/DOWN INPUT is low. Multiple
packages can be connected in either a parallel-
clocking or a ripple-clocking arrangement as shown
in cascading counter packages. Parallel clocking
provides synchronous control and hence faster re-
sponse from all counting outputs. Ripple-clocking
allows for longer clock input rise and fall times.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress ratingonly 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.
