The 74HC390N is a dual decade Ripple Counter is a high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL ). This is specified in compliance with JEDEC standard no-7A. This is a dual 4-bit decade ripple counters divided into four separately clocked sections. The counter has two divide-by-2 sections and two divide-by-5 sections. These sections are normally used in a BCD decade or bi-quinary configuration, since they share a common master reset input (nMR). If the two master reset inputs (1MR and 2MR) are used to simultaneously clear all 8-bit of the counter. The separate clocks (nCP 0 and nCP 1) of each section allow ripple counter or frequency division applications of divide-by-2/4/5/10/20/25/50/100.

• Two BCD decade or binary counters
• Two master reset inputs to clear each decade counter individually
• Standard output capability
• MSI ICC category
