Description

The 74LS02 is a quad 2-input NOR gate IC from the 74LS series of logic devices. It consists of four independent NOR gates, each having two inputs. A NOR gate outputs LOW when any of its inputs is HIGH, and only outputs HIGH when all inputs are LOW. This IC is commonly used in digital logic circuits where NOR logic operations are required. It is part of the LS (Low Power Schottky) family, offering faster operation and lower power consumption compared to standard TTL logic.

Features

  • Quad 2-input NOR gates: Four independent NOR gates in one package.
  • Low power consumption: Low-power Schottky technology reduces power dissipation.
  • High-speed operation: Fast switching performance.
  • Wide operating voltage range: Typically operates from 4.75V to 5.25V.
  • TTL compatible inputs and outputs.
  • Standard 14-pin DIP package: Suitable for breadboards and through-hole PCB designs.

Specifications

  • Logic Family: 74LS (Low Power Schottky TTL)
  • Number of Gates: 4 NOR gates (2 inputs each)
  • Number of Inputs per Gate: 2
  • Operating Voltage Range: 4.75V to 5.25V
  • Typical Supply Voltage: 5V
  • Low Power Dissipation: ICC = 1 mA (typical)
  • Propagation Delay (typical): 10 ns
  • Low-level Output Voltage (VOL): 0.4V (max)
  • High-level Output Voltage (VOH): 2.7V (min)
  • Input Current: 1.6 mA (typical per gate)
  • Temperature Range: 0°C to +70°C (commercial grade)
  • Pin Count: 14 pins (DIP-14 package)
