CD4086 (Quad 2-input (XOR) Gate)

The CD4086 is a CMOS Quad 2-input Exclusive-OR (XOR) Gate integrated circuit (IC). It belongs to the 4000 series of CMOS logic ICs and is commonly used in digital circuits where logical XOR operations are required. The CD4086 has four independent XOR gates in a single 14-pin package.

Key Features of CD4086:

1. Logic Function:

• The CD4086 contains four 2-input XOR gates. An XOR gate outputs high (1) when the number of high inputs is odd (i.e., one input is high and the other is low). If both inputs are the same (either both low or both high), the output is low (0).
• The truth table for a 2-input XOR gate is as follows:
• A B Output (A XOR B) 0 0 0 0 1 1 1 0 1 1 1 0

1. Voltage Range:

• The CD4086 operates over a wide voltage range, typically from 3V to 15V, which is suitable for use in both low-voltage and higher-voltage digital systems. It can interface with TTL (Transistor-Transistor Logic) as well as other CMOS logic systems.

1. Package Type:

• The CD4086 is available in various package forms, including the DIP-14 (Dual In-Line Package) and SOIC (Surface Mount) packages.

1. Low Power Consumption:

• As a CMOS IC, the CD4086 consumes very little power when not actively switching. It is highly energy-efficient, which is a key feature of CMOS technology.

1. High Noise Immunity:

• Being a CMOS device, it has excellent noise immunity, which makes it more reliable in noisy environments compared to TTL logic gates.

1. Output Drive Capability:

• The IC can drive standard CMOS outputs, providing enough current to drive external devices like LEDs or logic gates without requiring additional buffering.

1. Temperature Range:

• The typical operating temperature range for the CD4086 is -55°C to +125°C, which makes it suitable for use in both commercial and industrial applications.
