CD4071 Quad 2-Input OR Gate IC (DIP)

Overview: CD4071 Quad 2-Input OR Gate IC (DIP)

The CD4071 is a CMOS Quad 2-Input OR Gate IC that integrates four independent OR gates into a single 14-pin DIP package. Each gate outputs a logic HIGH when one or both inputs are HIGH, following standard OR logic. Built with CMOS technology, the CD4071 delivers low static power consumption, wide supply voltage tolerance, and strong noise immunity, making it well suited for a broad range of digital logic and interfacing applications.

Key Features

• Four independent 2-input OR gates in one IC
• Wide supply voltage range: 3 V to 15 V for flexible designs
• CMOS design ensures low quiescent current and high input impedance
• High noise immunity and robust switching for reliable operation
• Compatible with TTL and CMOS logic families for easy interfacing
• Standard 14-pin DIP package for straightforward prototyping
• Propagation delay and transition times suitable for standard digital applications

Typical Logic Function

Each 2-input gate implements OR logic. The output is HIGH when either input A or input B is HIGH.

• Input A = 0, Input B = 0 -> Output = 0
• Input A = 0, Input B = 1 -> Output = 1
• Input A = 1, Input B = 0 -> Output = 1
• Input A = 1, Input B = 1 -> Output = 1

Technical Specifications

• Package: 14-pin DIP
• Number of gates: 4 independent 2-input OR gates
• Supply voltage (Vcc): 3 V to 15 V
• Logic family: CMOS (TTL compatible levels)
