The NXP 74F259N is a high-performance silicon-gate CMOS device that combines low static and dynamic power consumption with high speed and high output drive. This 8-bit addressable latch is designed to be used in a wide range of digital applications, from microprocessor systems to data storage and retrieval systems.
Key Features
- Integrated Circuit Type: The 74F259N is an addressable latch, which allows for selective storage and retrieval of data bits.
- Logic Family: This device belongs to the 74F series, known for its fast speeds, which make it suitable for high-performance systems.
- Package: The device is housed in a standard 16-pin DIP (Dual In-line Package), making it compatible with breadboards and standard PCB layouts.
- Operating Voltage: It operates at a nominal voltage of 5V, which is typical for TTL (Transistor-Transistor Logic) devices.
- Output Capability: The 74F259N can drive 15 LSTTL loads, providing ample current for most applications.
- Power Dissipation: It has a low power consumption, which is a critical aspect for energy-efficient designs.
Functionality
The 74F259N consists of eight latches with three-state outputs for bus organized system applications. Each latch is addressable by means of a 3-bit binary address for data input. A single active LOW enable (E) can be used to latch the data. When the enable input is HIGH, the latches remain in their previous state.
Applications
With its ability to handle fast data inputs and provide stable data storage, the NXP 74F259N is ideal for a variety of digital applications, including:
- Microprocessor systems
- Data storage and retrieval systems
- Communication systems
- Instrumentation and control systems
Its robust design and ease of integration make the NXP 74F259N a reliable and versatile component for designers looking to optimize their digital systems for speed and power efficiency.
