Be the first to review “7486 Quad EXCLUSIVE-OR Gate”

Function:

Implements the EXCLUSIVE-OR (XOR) logic function with four independent XOR gates.

Logic Operation:

Output is high (1) if an odd number of inputs are high. For inputs A and B,
𝐴⊕𝐵
A⊕B is true if either A or B is true, but not both.

Inputs:

Four XOR gates, each with two inputs (A and B).

Outputs:

Four outputs, one for each XOR gate.

Power Supply:

Operates at 4.75V to 5.25V (standard 5V TTL logic).

Current:

Input Current: Low (typically a few microamperes).
Output Drive Current: Up to 8 mA.

Propagation Delay:

Approximately 8-15 ns.

Temperature Range:

0°C to 70°C (commercial grade) or -40°C to 85°C (industrial grade).

Package Types:

DIP-14, SOIC-14, TSSOP-14, and other surface-mount packages.
