LC08A (SN74LVC08A) Quad AND Gate: A Reliable Logic Solution for Modern Digital Projects
When working on digital logic designs, microcontrollers, or embedded systems, having a solid set of basic logic gates is essential. One part that frequently appears in many projects is the LC08A, which is the marking code for the SN74LVC08A from Texas Instruments.
The SN74LVC08A is a quadruple 2-input positive-AND gate that operates at low voltage, making it very popular in 3.3V systems.
Key Features of LC08A / SN74LVC08A:
Quad 2-Input AND Gates (4 independent gates in one package)
Wide supply voltage range: 1.65V to 3.6V
High-speed operation (up to 100MHz typical)
Excellent signal integrity with 5V tolerant inputs (in many configurations)
Strong output drive capability
Available in multiple packages: SOIC-14, TSSOP-14, VQFN, etc.
Industrial temperature range: -40°C to +125°C
Signal conditioning and logic combination in MCU projects
Enabling/disabling circuits
Interface logic between different voltage domains
Embedded systems and IoT devices
Educational electronics and prototyping
Even though it’s a basic logic IC, the LVC family (Low Voltage CMOS) makes the LC08A very useful when you need fast, low-power logic at 3.3V — which is the standard for most modern STM32, ESP32, and ARM-based designs.
While this chip is still actively produced, certain package types or small batch quantities can sometimes be tricky to source quickly from major distributors. Many engineers have turned to Veswin, a professional electronic components distributor that maintains good stock of TI logic ICs including the LC08A / SN74LVC08A series. They offer genuine parts with proper traceability.
