MM74HC393 Dual 4-Bit Binary Counter
MM74HC393
Dual 4-Bit Binary Counter
General Description
The MM74HC393 counter circuits contain independent rip-
ple carry counters and utilize advanced silicon-gate CMOS
technology. The MM74HC393 contains two 4-bit ripple
carry binary counters, which can be cascaded to create a
single divide-by-256 counter.
Each of the two 4-bit counters is incremented on the HIGH-
to-LOW transition (negative edge) of the clock input, and
each has an independent clear input. When clear is set
HIGH all four bits of each counter are set to a low level.
This enables count truncation and allows the implementa-
tion of divide-by-N counter configurations.
Each of the counters outputs can drive 10 low power
Schottky TTL equivalent loads. This counter is functionally
as well as pin equivalent to the 74LS393. All inputs are pro-
tected from damage due to static discharge by diodes to
V
CC
and ground.

Recommended Operating
Conditions
Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dissipation temperature derating — plastic “N” package: −
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 4)
Note 4: For a power supply of 5V ±10% the worst case output voltages (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
= 5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage cur-
rent (I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
