Frequently Asked Questions
What is the SN74AS298AD and what is its primary logic function?
The SN74AS298AD is a quad 2-input multiplexer with storage from Texas Instruments in the AS (Advanced Schottky) logic family. It contains 4 multiplexer functions with integrated storage capability, allowing data selection and latching in a single 16-pin SOP device. This makes it highly useful in data path control and bus switching applications.
What are the key electrical specifications of the SN74AS298AD?
The SN74AS298AD features a load capacitance of 50 pF, a maximum output low current (I_OL) of 48 mA, and operates in the AS logic family known for high-speed performance. The 16-pin SOP package (JESD-30 code R-PDSO-G16) supports surface-mount assembly, and the device is rated for a 15-year YTEOL, indicating reliable long-term supply availability.
What package does the SN74AS298AD come in and what are its RoHS credentials?
The SN74AS298AD is packaged in a 16-pin SOP (Small Outline Package) with JESD-30 code R-PDSO-G16, suitable for standard surface-mount PCB assembly. It is fully lead-free and RoHS compliant per JESD-609 Code e4, making it compatible with environmentally conscious manufacturing processes and European RoHS regulations.
What are common applications for the SN74AS298AD?
Common applications include data bus multiplexing, register file input selection, and pipeline stage data routing in high-speed digital logic systems. The storage capability allows the SN74AS298AD to be used as a registered multiplexer in microprocessor glue logic, DSP data paths, and FPGA companion circuits where synchronous data capture and selection are needed simultaneously.
How does the SN74AS298AD compare to other multiplexer ICs in terms of speed?
As part of the AS (Advanced Schottky) family, the SN74AS298AD offers higher switching speed compared to standard TTL and HC-family multiplexers. The AS family delivers propagation delays in the low nanosecond range, making the SN74AS298AD suitable for systems operating at high clock frequencies where setup and hold times are critical for data integrity.
