CD4048BM  

Multi-Function, Configurable Gates and Inverters

CD4048BM Description

The CD4048BM from Texas Instruments is a multifunction expandable logic gate IC belonging to the 4000B series, designed for versatile digital logic applications. Packaged in a 16-SOIC tube, this surface-mount device operates across a wide voltage range (3V to 18V), making it suitable for both low-power and industrial-level designs. With 8 inputs and a single circuit, it supports configurable logic functions (AND, OR, NAND, NOR, etc.), offering flexibility in system design. The IC is ROHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited shelf life), ensuring reliability in harsh environments.

CD4048BM Features

• Multifunction Logic: Configurable as AND, OR, NAND, NOR, or expandable gate, reducing the need for multiple discrete ICs.
• Wide Voltage Range (3V–18V): Compatible with TTL, CMOS, and mixed-voltage systems.
• High Output Drive (6.8mA sink/source): Capable of driving moderate loads directly.
• Low Power Consumption: Ideal for battery-operated or energy-efficient designs.
• Expandable Inputs: Cascadable for larger logic arrays, enhancing scalability.
• Robust Packaging: 16-SOIC for compact PCB layouts and automated assembly.
• Industrial Compliance: ROHS3, REACH, and ECCN EAR99 certified for global use.

CD4048BM Applications

• Programmable Logic Arrays (PLAs): Custom logic function implementation.
• Signal Conditioning: Noise filtering and level shifting in mixed-voltage systems.
• Industrial Control Systems: Relay drivers, sensor interfacing, and logic expansion.
• Consumer Electronics: Remote controls, timers, and display drivers.
• Automotive Electronics: Non-critical logic functions in dashboards or lighting.
• Legacy System Upgrades: Replacement for obsolete logic ICs due to broad compatibility.

Conclusion of CD4048BM

The CD4048BM stands out for its versatility, wide voltage range, and high drive capability, making it a cost-effective solution for complex logic designs. Its expandable functionality reduces component count, while industrial-grade reliability ensures longevity. Though marked for last-time buy, it remains a pragmatic choice for legacy systems or designs requiring configurable logic with minimal footprint. Engineers should consider this IC for flexible, low-power, and noise-immune applications where standard gates fall short.
