Overview

The Nexperia HEF4071BT is a robust quad 2-input OR gate IC from the venerable 4000B CMOS logic family, designed for general-purpose digital logic operations. Its primary function is to implement boolean OR logic, where an output is HIGH if any of its inputs are HIGH. A critical design consideration for this part is its relatively slow propagation delay of 20 ns, which, while acceptable for many control and sequencing tasks, necessitates careful timing analysis in high-speed data paths to avoid metastability or race conditions. This makes it ideal for applications where deterministic logic is prioritized over raw speed.

Key Features

Quad 2-Input OR Gate Configuration
Wide Operating Supply Voltage: 3 V to 15 V
Propagation Delay: 20 ns (typical)
Output Drive: ±3.4 mA (Low/High Level)
Operating Temperature Range: -40°C to +125°C
Package: SOIC-14 (8.75mm x 4mm x 1.45mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Simple combinatorial logic functions in embedded controllers
Signal gating and multiplexing in industrial automation
Power sequencing and enable logic for subsystems
Status indication and alarm generation circuits
