Texas Instruments SN54ALS259 8-Bit Addressable Latches SNJ54ALS259J

The SN54ALS259 is an 8-bit addressable latch designed for general-purpose storage applications in digital systems. It features asynchronous parallel clear and an active-high decoder, making it suitable for use as working registers, serial-holding registers, and demultiplexers. The device supports four distinct functional modes, including addressable latch mode, memory mode, 1-of-8 decoding, and clear mode, which can be selected by controlling the clear (CLR) and enable (G) inputs. This part operates over a military temperature range of -55¬8C to 125¬8C, ensuring reliability in demanding environments. The SN54ALS259 is available in a 16-pin ceramic dual in-line package (CDIP), facilitating integration into various circuit designs. Its expandable nature allows for use in n-bit applications, making it versatile for different project requirements.
