What is SN74ALB16244DLG4 used for?
The SN74ALB16244DLG4 is commonly used for address and data bus buffering in memory interfaces, processor expansion boards, and backplane bus drivers operating at 3.3 V logic levels. Its 16-bit width and 3-state outputs make it well suited for multiplexed bus architectures in networking equipment, industrial controllers, and FPGA development platforms. The part also serves as a signal fanout buffer in systems where one logic source must drive multiple downstream loads without degrading signal integrity.

Frequently Asked Questions
How many bits can the SN74ALB16244DLG4 buffer simultaneously and how does that help address bus designs?
The SN74ALB16244DLG4 buffers 16 bits in a single IC, which is enough to drive a full 16-bit address or data bus from a microprocessor, reducing the number of discrete buffer chips and simplifying PCB routing on memory expansion boards.
What load capacitance per output can the SN74ALB16244DLG4 drive, and how does that affect PCB trace length?
Each output of the SN74ALB16244DLG4 is characterized at a load capacitance of 50 pF, which corresponds to moderate PCB trace lengths of roughly 100 mm to 200 mm at 3.3 V logic levels, sufficient for most backplane and expansion card designs.
Since SN74ALB16244DLG4 has a YTEOL of 0, what are the procurement and lifecycle risks for new designs?
A YTEOL rating of 0 indicates this part may be at or near end-of-life, which means procurement teams should confirm current active status with Texas Instruments, evaluate available stock at franchised distributors, and consider last-time-buy orders or migration to a supported successor device.
