HEF4070BT,652

HEF4070BT,652 Description

The HEF4070BT,652 from Nexperia is a quad 2-input XOR (Exclusive OR) gate IC belonging to the 4000B series, designed for high-reliability digital logic applications. Packaged in a 14-pin SOIC (Surface Mount) tube, this device operates across a 3V to 15V supply range, making it versatile for both low-voltage and industrial-level systems. With a maximum propagation delay of 55ns at 15V and 50pF load, it balances speed and power efficiency, drawing only 4 µA quiescent current. Though marked as obsolete, it remains a robust choice for legacy designs due to its ROHS3 compliance and REACH-unaffected status.

HEF4070BT,652 Features

• Quad XOR Gates: Four independent XOR gates in a single package, reducing board space and complexity.
• Wide Voltage Range (3V–15V): Supports diverse applications from battery-powered devices to industrial systems.
• Low Power Consumption: Ideal for energy-sensitive designs with a quiescent current of just 4 µA (max).
• Balanced Output Drive: 3mA output current (high/low) ensures reliable signal integrity.
• Noise Immunity: Input logic levels (1.5V–4V low, 3.5V–11V high) provide robust noise margins.
• MSL 1 (Unlimited): Suitable for extended storage without moisture sensitivity concerns.

HEF4070BT,652 Applications

• Digital Signal Processing: Parity generation/checking, error detection, and arithmetic circuits.
• Industrial Control Systems: Logic-level translation and signal conditioning in harsh environments.
• Consumer Electronics: Used in remote controls, encoders, and data encryption circuits.
• Legacy System Maintenance: Replacing older 4000-series logic in repairs or upgrades.

Conclusion of HEF4070BT,652

The HEF4070BT,652 excels in low-power, high-noise-immunity applications, offering a reliable XOR logic solution despite its obsolete status. Its wide voltage range and compact integration make it a pragmatic choice for designers needing backward compatibility or cost-effective logic functions. While newer alternatives exist, this IC remains a proven performer in industrial, automotive, and consumer electronics where robustness is paramount.
