74HC4024
7-stage binary ripple counter
Rev. 9 — 28 April 2016
Product data sheet
1. General description
The 74HC4024 is a 7-stage binary ripple counter with a clock input (CP), an overriding
asynchronous master reset input (MR) and seven fully buffered parallel outputs (Q0 to
Q6). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears
all counter stages and forces all outputs LOW, independent of the state of CP. Each
counter stage is a static toggle flip-flop. Schmitt-trigger action in the clock input makes the
circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes. This
enables the use of current limiting resistors to interface inputs to voltages in excess of
V
CC
.
2. Features and benefits
Low-power dissipation
Complies with JEDEC standard no. 7A
CMOS input levels
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V.
Multiple package options
Specified from
40 C
to +80
C
and from
40 C
to +125
C.
3. Applications
Frequency dividing circuits
Time delay circuits.
