Frequently Asked Questions
What is the operating voltage range of the SN74HC259D?
The SN74HC259D operates over a supply voltage range of 2V to 6V, making it compatible with both 3.3V and 5V logic systems. This wide voltage range allows the device to interface with various microcontrollers and digital logic families without level-shifting circuitry.
How does the addressable latch function work in the SN74HC259D?
The SN74HC259D uses a 3-bit address input (A0, A1, A2) to select one of 8 latch outputs. Data on the D input is routed to the selected latch when the chip enable is active, while the remaining 7 latches retain their previous state. This 1:8 demultiplexer followed by latch architecture enables efficient control of 8 independent outputs using only a 3-bit address plus one data line.
What are typical applications for the SN74HC259D?
The SN74HC259D is commonly used in output port expansion, LED display driving, relay and solenoid control, and programmable logic applications. It is also suitable for industrial automation panels, embedded system peripheral control, and any design requiring individually addressable latched digital outputs with minimal I/O pin usage on the host controller.
What package type is the SN74HC259D available in and what is the pin count?
The SN74HC259D is available in a 16-pin SOIC (Small Outline Integrated Circuit) package, designated by the 'D' suffix. This surface-mount package has a standard 1.27mm pin pitch, making it suitable for automated PCB assembly and compact board designs requiring reliable soldering and good thermal performance.
