Texas Instruments SN74LS390NG4 is a dual decade counter IC from the 74LS series. This component features two independent 4-bit ripple counters, each capable of counting up to decade (divide-by-10) functionality. The counters are triggered by a negative edge. Each 4-bit element can be configured as divide-by-2 and divide-by-5 counters, allowing for flexible frequency division. A common clock input and an enable input are provided for each counter. The SN74LS390NG4 offers asynchronous reset capability for both counters. It operates within a supply voltage range of 4.75V to 5.25V and has a maximum count rate of 35 MHz. The device is housed in a 16-pin Dual In-line Package (PDIP) suitable for through-hole mounting. This component is commonly utilized in digital logic applications, including frequency synthesis, timing circuits, and control systems within industrial and consumer electronics.
