The NEC D17147GT-584 is a semiconductor component, specifically a gate array IC. Below are the factual details about this part:

Manufacturer:

• NEC (Nippon Electric Company, now part of Renesas Electronics Corporation)

Specifications:

• Type: Gate Array (Semi-custom IC)
• Package: Likely a DIP (Dual In-line Package) or another through-hole package (exact package type may vary)
• Technology: CMOS or BiCMOS (exact process technology depends on the series)
• Operating Voltage: Typically 5V (common for older gate arrays)
• Pin Count: Likely 28-pin or higher (exact count depends on variant)
• Speed: Moderate (exact propagation delay depends on internal configuration)

Descriptions:

• The D17147GT-584 is a mask-programmable gate array, meaning it is customized during manufacturing for specific logic functions.
• Designed for digital logic applications, such as control systems, interface logic, or custom ASIC-like functions.
• Used in older electronics, industrial controls, or telecommunications equipment.

Features:

• Configurable Logic Cells: Contains uncommitted logic gates that can be interconnected via metal mask layers.
• Standard I/O Interfaces: Supports TTL or CMOS-compatible input/output levels.
• Low Power Consumption: (Compared to full-custom ICs, depending on configuration.)
• Reliable for Harsh Environments: Some NEC gate arrays were designed for industrial use.

Notes:

• Since this is an older part, datasheets may be scarce.
• Exact performance metrics depend on the final customized design.
