74HC259 8-Bit Addressable Latch, DIP-16

8-Bit Addressable Latch, 74HC259

The 74HC259 is an 8-bit addressable latch designed for general-purpose storage applications in digital systems. This versatile IC can store single-line data in eight addressable latches and also function as a 1-of-8 decoder or demultiplexer with active-high outputs.

It offers four distinct modes of operation: addressable-latch, memory, 1-of-8 decoding, and active-high demultiplexing. These modes are selectable by controlling the clear (CLR) and enable (G) inputs, giving you flexibility for a wide range of logic designs.

Features

• High-current inverting outputs drive up to 10 LSTTL loads
• 8-bit parallel-out storage register performs serial-to-parallel conversion with storage
• Asynchronous parallel clear
• Active-high decoder
• Enable input simplifies expansion
• Expandable for n-bit applications
• Low power consumption: 80µA maximum
• Fast propagation delay: 14ns typical
• Wide supply voltage range: 2V to 6V
• Operating temperature range: -40°C to 85°C

Applications

This latch is ideal for industrial control systems, digital data storage, and logic circuitry where reliable data latching and decoding are required. Its multifunctional nature makes it a valuable component in many electronic projects.

The IC comes in a 16-pin DIP package for easy integration into through-hole circuit boards. With its robust specifications and standard logic family, the 74HC259 is a dependable choice for your digital design needs.
