74HC390 counter equivalent, dual decade ripple counter.
* Two BCD decade or bi-quinary counters
* One package can be configured to divide-by-2, 4, 5, 10, 20, 25, 50 or 100
* Two master reset inputs to clear each de.
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.
The 74HC/HCT390 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT390 are dual 4-bit decade ripple counters divided into four separ.
