74HC390PW

Dual decade ripple counter

The 74HC390; 74HCT390 is a dual 4-bit decade ripple counter divided into four separately clocked sections. The counters have two divide-by-2 sections and two divide-by-5 sections. These sections share an asynchronous master reset input (nMR) and can be used in a BCD decade or bi-quinary configuratio; ? Input levels:? For 74HC390: CMOS level\n? For 74HCT390: TTL level\n\n? Two BCD decade or bi-quinary counters\n? One device can be configured to divide-by-2, 4, 5, 10, 20, 25, 50 or 100y\n? Two master reset inputs to clear each decade counter individually\n? Specified in compliance with JEDEC stand;
