Texas Instruments SN74HCT32N Quad 2-Input OR Gate IC, DIP14

The Texas Instruments SN74HCT32N is a high-speed CMOS logic gate, specifically a 2-input quadruple positive-OR gate. It is designed to perform the fundamental Boolean logic function Y=(A+B) in positive logic, making it an essential building block for a wide variety of digital circuits.

This integrated circuit is renowned for its low power consumption, drawing a maximum of just 20µA, which is crucial for battery-powered or energy-efficient designs. Despite its low power draw, it delivers robust performance with a typical propagation delay (tpd) of 13ns and can drive up to 10 Low-Power Schottky (LSTTL) loads, ensuring compatibility and strong signal integrity in mixed-logic environments.

A key feature is its TTL-voltage compatible inputs, which allow it to interface seamlessly with older TTL logic families without requiring additional level-shifting components. This simplifies design and increases flexibility in system integration. The outputs provide a solid ±4mA drive current at 5V, capable of sourcing or sinking sufficient current for LEDs, relays, or other logic inputs.

The device is housed in a durable, through-hole 14-pin DIP (Dual In-line Package), making it perfectly suited for prototyping on breadboards, use in educational settings, or for permanent installation in robust industrial control systems. Its wide operating temperature range from -40°C to 85°C ensures reliable performance in demanding environmental conditions.

Key Applications:

• Industrial Control Systems: For logic processing in PLCs and automation equipment.
• Data Routing & Selection: Used in multiplexers, adders, and other arithmetic logic units (ALUs).
• Signal Gating & Conditioning: Combining multiple control or data signals.
• Prototyping & Education: An ideal component for learning digital electronics and building circuit prototypes.
