74HC08 is a Quad 2-Input AND Gate integrated circuit. The AND gate is a logical operator that provides the logical high-one output when all of the inputs are high-one. For other conditions value will be low. Here we will discuss features of 74HC08, pinout, and other related functions.
74HC08 Introduction
- The 74HC08 provides comes with 4 independent 2 input AND gates having standard push-pull outputs. It has features to operate for different voltage ranges from 2.0V to 6.0V.
- 74HC08 comes with the same pinout configuration as LS08. The device input is supported to CMOS outputs, through pullup resistors, and supported to LSTTL output.
- It has a protection circuit for protection due ot high static voltage or electric fields. Some precautions taken to avoid voltage high values as compared to the maximum rating voltage of the high−impedance circuits.

How to Use the 74HC08 in a Circuit
- First of all, make the connection of Vcc pin 14 with positive supply voltage in the range of (2.0V to 6.0V).
- Then connect GND pin 7 with the ground for the power supply
- Provide input signal to A and B inputs at required AND gate.
- Output Y of every gate will be HIGH if both input A and B have 1 or high value

What is the brief description of 74LS08?
- 74LS08 is a Quadruple 8-bit Two Input AND IC. Gate AND gate is a digital circuit used for conversion logic conditions in certain logic states. AND gate two logic state signals are used. First is HIGH called as 3 to 5 Volts and 2nd is LOW which is denoted as 0-2.6Volts
What is a 74HC series?
- 74HC group of ICs comes with high sped, low power that uses CMOS configuration. The devices are pins-supported come with different devices like 74TTL, 74STTL, and 4000 series. 2V to 6V operation voltage and has Very high impedance inputs.
Is 74HC better than 74LS?
- 74HC series based on CMOS configuration that performs the 74LS series for power use noise immunity and larger voltage support. So best to use it for digital application
What is the difference between 74HC and 74HCT?
- The basic difference is the input circuit. The output of these series can operate LSTTL or CMOS, but the 74HCT inputs have TTL-level supported thresholds.
Is 74HC TTL or CMOS?
Code | Family | Vcc |
