7408 IC Quad 2-Input AND Gate DIP-14

7408 IC Quad 2-Input AND Gate 14 Pins DIP 7408 Logic IC In this guide, you will learn what the 74×08 IC does and how to hook it up in a circuit. What does the 74C08 / 74LS08/7408 do? The 74×08 gives you four basic AND gates that can be used individually. An AND gate is a logic gate that outputs 1 (HIGH) only if all of its inputs are 1 (HIGH). In the truth table below, you can see what the output will be for any given input: The truth table for the AND gate How To Use This Chip Like every other chip in the 7400 series, this IC needs to be connected to power before you can use it. Most 7400 ICs support a VCC voltage of 5V. One difference between the HC and LS versions of the chip is that the 74HC08 supports 2V to 6V, while the 74LS08 supports only 5V. Once it’s connected, you can use any of the four basic AND gates inside. The 74HC08/74LS08 IC connected to power The amount of current you can pull out of each AND gate depends on which chip you are using. 74HC08: Each output can sink or source 4 mA when powered with 5V. 74LS08: HIGH-Level Output Current: 0.4 mA LOW-Level Output Current: 8 mA 74×08 Pinout The 74×08 has 14 pins and contains four basic AND gates laid out as shown in the pinout diagram below: Pin Name Pin # Type Description 1A 1 Input Input to the first AND gate. 1B 2 Input Input to the first AND gate. 1Y 3 Output Output from the first AND gate. 2A 4 Input Input to the second AND gate. 2B 5 Input Input to the second AND gate. 2Y 6 Output Output from the second AND gate.

7408 IC Quad 2-Input AND Gates The 7408 IC, available in popular versions like the 74HC08, is a logic gate chip that performs the Boolean AND function. This means the output of each of the four internal gates will be HIGH (logic 1) only when both of its inputs are HIGH. If either or both inputs are LOW (logic 0), the output will be LOW. Its straightforward functionality and ease of use make it an essential component for both hobbyists and professionals in electronics.
