概要

Description

SN74HC03DR is a hex (six) 2-input OR gate in the TI 74HC CMOS family. It contains six independent OR gates; each gate outputs Y = A OR B. It operates from a 2V to 6V supply (commonly 5V) with CMOS input thresholds and standard CMOS outputs. The “DR” suffix denotes a RoHS-compliant surface-mount package (14 pins). Uses include combining signals, simple logic gating, and building basic digital circuits in microcontroller projects. Good practice: provide decoupling on Vcc, tie unused inputs, and respect input/output current limits and propagation delays.

Features

Here are the key features of SN74HC03DR:
- Quad 2-input AND gates (four independent AND gates)
- High-speed CMOS (74HC) logic
- Wide supply voltage: 2 V to 6 V (5 V common)
- Low static power dissipation
- CMOS input/output with high noise margins
- Typical propagation delay in the low tens of nanoseconds range at 5 V
- Operating temperature: -40°C to +125°C
- 14-pin package (SOIC) with DR/tape-and-reel variant available
Useful for creating complex logic with multiple AND gate needs while maintaining fast, low-power operation.

Package

SN74HC03DR is a 14‑pin small‑outline IC in an SOIC (D) package, with Tape & Reel packaging (the “R” suffix).

Pinout

- Pin count: 14 pins
- Function: Quad 2-input NOR gate (four independent NOR gates: A1,B1→Y1; A2,B2→Y2; A3,B3→Y3; A4,B4→Y4)

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other semiconductors.

Application
