Dual Decade Ripple Counter
September 1997 - Revised October 2003
Features
Description
• Two BCD Decade or Bi-Quinary Counters
The CD74HC390 and ’HCT390 dual 4-bit decade ripple
counters are high-speed silicon-gate CMOS devices and are
pin compatible with low-power Schottky TTL (LSTTL). These
devices are divided into four separately clocked sections.
The counters have two divide-by-2 sections and two divideby-5 sections. These sections are normally used in a BCD
decade or bi-quinary configuration, since they share a common master reset (nMR). If the two master reset inputs (1MR
and 2MR) are used to simultaneously clear all 8 bits of the
counter, a number of counting configurations are possible
within one package. The separate clock inputs (nCP0 and
nCP1) of each section allow ripple counter or frequency division applications of divide-by-2, 4. 5, 10, 20, 25, 50 or 100.
Each section is triggered by the High-to-Low transition of the
input pulses (nCP0 and nCP1).
• One Package Can Be Configured to Divide-by-2, 4,
5,10, 20, 25, 50 or 100
• Two Master Reset Inputs to Clear Each Decade
Counter Individually
• Fanout (Over Temperature Range)
- Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
• Wide Operating Temperature Range . . . -55oC to 125oC
• Balanced Propagation Delay and Transition Times
• Significant Power Reduction Compared to LSTTL
Logic ICs
For BCD decade operation, the nQ0 output is connected to
the nCP1 input of the divide-by-5 section. For bi-quinary
decade operation, the nO3 output is connected to the nCP0
input and nQ0 becomes the decade output.
• HC Types
- 2V to 6V Operation
- High Noise Immunity: NIL = 30%, NIH = 30% of VCC
at VCC = 5V
The master reset inputs (1MR and 2MR) are active-High
asynchronous inputs to each decade counter which operates on the portion of the counter identified by the “1” and “2”
prefixes in the pin configuration. A High level on the nMR
input overrides the clock and sets the four outputs Low.
• HCT Types
- 4.5V to 5.5V Operation
- Direct LSTTL Input Logic Compatibility,
VIL= 0.8V (Max), VIH = 2V (Min)
- CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH
