MC74VHCT259ADR2G

MC74VHCT259ADR2G Description

The MC74VHCT259ADR2G from onsemi is a high-performance 8-bit addressable latch designed for surface-mount applications. Part of the 74VHCT series, it operates within a 4.5V to 5.5V supply range, making it ideal for 5V TTL-compatible systems. This IC features a 1:8 demultiplexing circuit with standard output type, delivering 8mA source/sink current for robust signal integrity. With a propagation delay of just 6ns, it ensures high-speed data handling, while its ROHS3 compliance and REACH-unaffected status meet modern environmental standards. Packaged in a 16-SOIC Tape & Reel (TR), it suits automated assembly processes.

MC74VHCT259ADR2G Features

• High-Speed Operation: 6ns propagation delay for efficient data routing.
• Wide Voltage Range: 4.5V–5.5V compatibility with TTL levels.
• Balanced Output Drive: 8mA high/low current for stable signal transmission.
• Addressable Latch Function: 1:8 demultiplexing for flexible data distribution.
• Robust Packaging: 16-SOIC (TR) for automated PCB assembly.
• Environmental Compliance: ROHS3 and REACH-unaffected, ensuring eco-friendly use.
