About this product
Description
The SN74LS192N is a synchronous, positive-edge-triggered, 4-bit bidirectional decade counter IC in TTL logic, manufactured by Texas Instruments and housed in a standard 16-pin PDIP through-hole package. It counts synchronously in both up and down modes, functioning as a decade counter that counts in tens from 0 to 9 and back, making it well suited for a wide range of counting applications.
The IC features parallel data inputs (P0 - P3) that allow you to load an initial count value, giving flexibility in how counting operations start and proceed. This makes it a strong fit for frequency division circuits, clock generation, waveform modulation, pulse counting, and event sequencing in digital control systems. It operates with a dual-clock, clear-input configuration, allowing separate up/down clock lines along with a clear function to reset the count.
This chip is a classic building block in digital electronics education and hobbyist projects, commonly used alongside 7-segment displays, shift registers, and other TTL logic ICs to build counters, timers, and sequencing circuits.
