SN74LS399N3 is listed in the Flip Flops range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is D FLIP-FLOP, LS SERIES TTL. Review the specifications below when checking this part for your BOM.
The SN74LS399N3 is a quadruple 2-input multiplexer with storage manufactured by Texas Instruments. It belongs to the LS logic series and features four independent multiplexing channels, each equipped with a D flip-flop for data storage. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports through-hole mounting in a PDIP-16 package. It provides standard TTL-compatible inputs and outputs, designed for commercial temperature operation.
Verify the manufacturer part number SN74LS399N3 against official Texas Instruments documentation to confirm the specific suffix and package type. Ensure compatibility with existing circuit designs regarding voltage levels and pin configurations before procurement.
Select this component when designing systems requiring multiple selectable signal paths with data retention capabilities. Consider the LS logic speed and power consumption profile relative to system requirements and available PCB space for the PDIP-16 package.
This part is part of the Texas Instruments SN74LS series, which utilizes low-power Schottky technology. The SN74LS399 specifically addresses applications needing multiplexing with storage, distinguishing it from standard multiplexers without latches.
Compatible substitutes include other quadruple 2-input multiplexers with storage from the same logic family, such as the SN74LS399 or equivalent parts from other manufacturers adhering to the same pinout and electrical specifications.
