CD74AC08M

CD74AC08M Description

The CD74AC08M from Harris Corporation is a quad 2-input AND gate integrated circuit (IC) belonging to the 74AC series, designed for high-performance logic applications. Packaged in a 14-SOIC tube, this surface-mount device operates across a wide voltage range (1.5V–5.5V), making it versatile for mixed-voltage systems. With a maximum propagation delay of 8.7ns at 5V/50pF, it ensures fast signal processing, while its low quiescent current (4µA max) enhances power efficiency. Though marked obsolete, it remains relevant for legacy designs requiring robust logic gates with 24mA output drive capability (symmetric high/low).

CD74AC08M Features

• High-Speed Operation: 8.7ns propagation delay at 5V, ideal for timing-critical applications.
• Wide Voltage Range: Supports 1.5V–5.5V, enabling compatibility with TTL and CMOS interfaces.
• Low Power Consumption: Quiescent current ≤4µA reduces energy usage in battery-powered systems.
• Balanced Output Drive: 24mA sink/source current for driving capacitive loads or multiple inputs.
• Noise Immunity: AC-series technology ensures reliable performance in noisy environments.
• Compact Form Factor: 14-SOIC package saves board space in dense layouts.

CD74AC08M Applications

• Digital Signal Processing: Used in combinational logic circuits for arithmetic operations.
• Embedded Systems: Interfaces sensors/microcontrollers in industrial automation.
• Communication Devices: Signal conditioning in data transmission modules.
• Legacy Equipment Maintenance: Replaces older 74-series logic in repairs/upgrades.
• Power-Sensitive Designs: Suitable for portable electronics due to low static current.

Conclusion of CD74AC08M

The CD74AC08M excels in high-speed, low-power logic applications, offering a blend of performance and versatility. Its wide voltage tolerance and strong output drive make it a pragmatic choice for mixed-voltage systems, though its obsolete status necessitates alternative sourcing for new designs. Engineers value it for noise resilience and backward compatibility, particularly in industrial and communication hardware. For legacy projects or replacements, this IC remains a dependable solution.
