Product Overview: NXP 74HCT259N

The NXP 74HCT259N is a high-performance, 8-bit addressable latch designed for use in a wide range of digital applications. This integrated circuit (IC) is part of the 74HCT family, which is known for its high-speed CMOS technology. The 74HCT259N is compatible with TTL levels and is characterized by low power consumption, making it an excellent choice for interfacing with standard logic levels in mixed technology systems.

Key Features

• Logic Type: 8-bit addressable latch
• Supply Voltage Range: 4.5V to 5.5V
• High-Speed: Typical propagation delay time of 18ns
• Output Capability: Standard output drive, capable of driving 10 LSTTL loads
• Power Consumption: Low power dissipation with a typical I<sub>CC of 4μA

Functionality

The 74HCT259N is a versatile device that features an 8-bit memory ideal for addressable storage applications. It contains eight latches with 3-state outputs and can be used as either a demultiplexer or a memory device. It operates by storing the data presented on its inputs when the Latch Enable (LE) input is high. The data is retained when LE is low, and the address inputs (A0, A1, A2) select which latch output will be active.

Applications

With its robust design and ease of use, the 74HCT259N is suitable for various applications, such as:

• Data storage and retrieval
• Control systems
• Address decoding
• Signal routing
• Industrial electronics

Package and Quality

The NXP 74HCT259N is offered in a DIP-16 (Dual In-line Package) making it easy to handle and integrate into through-hole PCB designs. It is also available in other package options to suit different assembly requirements. The device is manufactured under NXP's stringent quality control processes, ensuring high reliability and performance consistency.

For designers and engineers looking for a reliable addressable latch solution, the NXP 74HCT259N offers the perfect blend of performance, power efficiency, and versatility to meet the needs of complex digital systems.
