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
