SN74LS161N is a 16-pin DIP (dual in-line package) integrated circuit manufactured by Texas Instruments. It is a 4-bit synchronous binary counter with a synchronous parallel load capability. Description: The SN74LS161N is a 4-bit synchronous binary counter. It has four independent J-K flip-flops with synchronous parallel load capability. It can count up or down depending on the state of the count enable (CE) and count up/down (CD) inputs. Features: Synchronous counting and loading Count up or down Synchronous parallel load capability High speed operation Low power consumption High noise immunity Applications: The SN74LS161N is used in a variety of applications including frequency division, pulse width modulation, and time delay generation. It is also used in digital clocks, timers, and counters.(For reference only)
