SNJ54ALS174J Hex/Quadruple D-Type Flip-Flops by Texas Instruments

The SNJ54ALS174J is a high-performance, integrated circuit from Texas Instruments, renowned for its reliability and precision. This device is part of the advanced low-power Schottky (ALS) family, which is designed to offer a superior balance between speed and power consumption. The SNJ54ALS174J specifically features six D-type flip-flops with direct clear inputs, making it an essential component for a wide range of digital applications.

Each flip-flop has an independent clear (CLR\) input and data (D) input. The clock (CLK) input is synchronous to all six flip-flops, ensuring that the state of each D input, when the CLK input is on a rising edge, is transferred to the corresponding flip-flop's output (Q). The clear function is asynchronous, and a low level at the CLR\ input sets all outputs to a low level, regardless of the other inputs. This feature is particularly useful for initializing registers and counters in digital systems.

The SNJ54ALS174J is encapsulated in a durable ceramic dual-inline package (DIP), which provides excellent thermal stability and resistance to harsh environmental conditions. This makes it suitable for military and aerospace applications that require components to operate reliably under extreme temperatures and stress.
