74HC390 Dual decade ripple counter

74HC390 Description

74HC390; 74HCT390 Dual decade ripple counter Rev.5 * 18 October 2021 Product data sheet 1.General .
The 74HC390; 74HCT390 is a dual 4-bit decade ripple counter divided into four separately clocked sections.

74HC390 Features

* Input levels:
* For 74HC390: CMOS level
* For 74HCT390: TTL level
* Two BCD decade or bi-quinary counters
* One device 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

74HC390 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 clock inputs (nCP0 and nCP1). 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 nQ3 output is connected t
