Frequently Asked Questions
What is the SN74ALS259N and what does it do?
The SN74ALS259N is an 8-bit addressable latch from Texas Instruments. It integrates a 1:8 demultiplexer followed by D-type latches, allowing individual bit addressing across 8 outputs. It operates with a 16-pin PDIP package and supports a 50pF load capacitance with 8mA output sink current, making it suitable for data storage and bus expansion in digital systems.
What is the reset behavior of the SN74ALS259N?
The SN74ALS259N features an active-high reset that is only active when the latch enable input is high. This means the reset function clears the addressed latch only during the enabled state, providing controlled and predictable reset behavior in sequential logic and state machine applications.
What applications is the SN74ALS259N suitable for?
The SN74ALS259N is ideal for microprocessor I/O port expansion, memory-mapped control registers, and industrial automation systems. Its 8-bit addressable architecture makes it popular in programmable logic controllers, embedded system design, and digital communication interfaces where selective bit latching across multiple outputs is required.
What is the package type and pin count of the SN74ALS259N?
The SN74ALS259N comes in a 16-pin R-PDIP-T16 (rectangular plastic dual-in-line) through-hole package. This standard DIP form factor makes it easy to use in breadboard prototyping and through-hole PCB production environments.
Are there alternative or compatible parts for the SN74ALS259N?
Compatible alternatives include the SN74LS259N (Low-power Schottky version) and SN74F259N (Fast logic version), both offering similar 8-bit addressable latch functionality in 16-pin DIP packages. SMD alternatives such as the SN74ALS259D in SOIC package are available for surface-mount designs requiring the same logic function.
