74LS390 DIP-16 Dual Decade Counter IC (74390, TTL, 5V)

Description -

The 74LS390 DIP is a TTL logic integrated circuit that functions as a dual decade counter in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for frequency division, event counting, and digital timing applications.

The device contains two independent decade counters, each consisting of a divide-by-2 stage and a divide-by-5 stage, which can be connected to provide a divide-by-10 counting function. The 74LS390 is widely used in digital clocks, timers, frequency dividers, and counter circuits.
