IC 8-Bit Latch Chip

The 74ALS996 component is designed for the commercial temperature range, while the 54ALS996 is available for operation within the military temperature range. Although both components are typically offered in the same package styles, this may change as the usage of the ALS family of parts declines. Therefore, while the 74xxx996 can be obtained in multiple package styles, the 54xxx996 may only be available in a different package style. It is essential to ensure that if a test board is initiated with a 74xx part, the corresponding 54xx part is also in stock for use in the final product.

The 74ALS996 and 54ALS996 are part of the 74xx series of integrated circuits, which are widely used in digital logic applications. The 74ALS996 is designed for commercial applications, providing reliable performance within standard temperature ranges, while the 54ALS996 is tailored for military applications, ensuring functionality in more extreme temperature conditions.

Both components serve as dual 4-bit multiplexers/demultiplexers, allowing for the selection of data inputs from multiple sources. This capability is essential in applications where data routing is critical, such as in communication systems, data acquisition systems, and digital signal processing. The multiplexing function enables efficient data management, reducing the number of required components and saving space on circuit boards.

Package styles for these components may include standard dual in-line packages (DIPs), surface mount packages (SMDs), or other configurations depending on the manufacturer. It is crucial to verify the availability of the desired package style when selecting components for a project, especially when transitioning from a test board using a 74xx part to a final product utilizing a 54xx part.

When designing circuits that incorporate these components, attention should be given to the electrical characteristics, such as supply voltage, input/output logic levels, and propagation delay. Additionally, understanding the thermal characteristics of the components is vital, particularly for applications that may expose the components to varying environmental conditions. By ensuring compatibility and availability of both the 74ALS996 and 54ALS996, designers can create robust, scalable systems that meet both commercial and military standards.The 74ALS996 part is shown which corresponds to the commercial temperature range, but the 54ALS996 may also be available which would operate up to the military temperature range. Although these parts are always available in the same packages, as the ALS family of parts starts to decline in usage that may no longer be true.

So while the 74xxx996 pa rt might be purchased in one or more package styles, the 54xxx996 might only be purchased in a completely different package style. In other words if you begin a test board with a 74xx part make sure the 54xx part is also still stocked if that is the part that will be used in the final product.
