The 74HC138 is a 3-to-8-line decoder/demultiplexer IC in a 14-pin DIP package, capable of decoding a 3-bit input into one of eight active-low outputs. Ideal for memory address decoding, bus systems, and control logic applications, high-speed (HC) options available.
The 74LS193 is a 4-bit synchronous binary counter with dual clock inputs, up/down control, and asynchronous reset. Ideal for applications in digital counting, frequency division, and control systems, it offers low power consumption and precise timing.
The 74LS/HC165 is an 8-bit parallel-in/serial-out shift register IC in a 14-pin DIP package. It converts parallel data inputs into a serial output, ideal for I/O expansion, sensor interfacing, and serial communication systems. Available in both LS and HC versions for low power and high-speed operation.
The 74LS151 is an 8-to-1 data selector/multiplexer in a 14-pin DIP package, designed to select one of eight input lines based on three selection inputs. Ideal for data routing, signal selection, and bus systems, it offers low power consumption and fast switching speeds.
The 74LS48 is a BCD to 7-segment decoder/driver IC in a 14-pin DIP package, designed to convert a 4-bit BCD input into the corresponding 7-segment display pattern for driving common cathode displays. It features internal pull-ups, low power consumption, and fast switching speeds.
The 74LS76 is a Dual J-K Flip-Flop in a 14-pin DIP package, featuring asynchronous preset and clear inputs. It provides reliable and high-speed state changes, making it perfect for use in sequential logic circuits, counters, and memory storage in digital systems.
