SN74HC259N

The SN74HC259N is an 8-bit addressable latch IC designed for general-purpose storage applications in digital systems. It is manufactured by Texas Instruments (TI) and belongs to the 74HC series of CMOS logic ICs. This device features eight individually addressable latches that can store single-line data and perform serial-to-parallel conversion with storage.

The SN74HC259N operates within a wide power supply voltage range of 2V to 6V, making it compatible with a variety of digital circuits. It includes active-high decoder enable inputs that simplify the expansion of the device for n-bit applications. Additionally, the IC has asynchronous parallel clear functionality, allowing for the clearing of all latches simultaneously.

With its low power consumption (80-µA max ICC typical) and high-current inverting outputs that can drive up to 10 LSTTL loads, the SN74HC259N is ideal for use in applications requiring high-speed data storage and retrieval. The typical propagation delay of 14 ns (plus or minus 4 ns) ensures fast and reliable data transfer.

The SN74HC259N is packaged in a variety of options, including PDIP, SOIC, SOP, TSSOP, and CDIP packages, making it suitable for different PCB design and mounting requirements. It is pin-compatible with other devices in the 74HC series, allowing for easy integration into existing systems.

In summary, the SN74HC259N is a versatile and high-performance 8-bit addressable latch IC that offers wide power supply voltage range, low power consumption, high-speed data transfer, and expandability for n-bit applications. Its compact packaging and pin compatibility make it suitable for use in a variety of digital systems and applications, including working registers, serial-holding registers, and active-high decoders or demultiplexers.
