CD74AC32MG4

Logic - Gates and Inverters

Gate is an electronic device responsible for carrying out Boolean logic operations in differently integrated circuits. They are the primary building blocks of digital circuits in various consumer electronics and computer components. Digital logic gate functions are normally performed by the flowing of current through the gate itself. Inverter is an electronic component, a type of logic gate, which utilizes an open collector or open drain transistor to give a low output impedance and reference voltage. CD74AC32MG4 is an advanced double-inverter gate component with bus interface designed and developed by Texas Instruments.

Application Field

The CD74AC32MG4 is a low-power, high-speed logic gates ideal for use in power constraints applications such as data acquisition systems and electronic controllers systems. It is commonly used in consumer electronics and communication systems including HDTVs, DVD players, VCRs and digital cameras. It is also used in computer peripherals like modems, routers and storage drives. In addition to that, CD74AC32MG4 is widely used in automotive infrastructure systems, embedded systems and robotics.

Working Principle

The devices contain four independent Schmitt-triggered 2-input inverter devices. The Schmitt-trigger action performs the double-inverting function as well as implementing input hysteresis which helps to maximize noise immunity on slowly changing input signals. This allows for improved device performance in harsh environments. Additionally, the devices offer a very low quiescent power supply current, which is suitable for battery-powered systems. The input logical “1” is defined with the range of 2.4V to 5V, and the input logical “0” is defined with the range of -0.3V to 0.8V. The device is capable of providing output maximum current of 16mA, with a minimum output voltage swing of 0.5V and maximum voltage swing of 4.5V. The propagation delay time is less than 1.75ns.

Conclusion

The CD74AC32MG4 are advanced double-inverter devices designed by Texas Instruments. It is well suited for various power constraint applications. It features lower quiescent current, low propagation delay time and high input output voltage swing which ensure improved device performance and minimum noise generated. Thus, the product is widely used in consumer electronics, embedded systems, communications and automotive infrastructures.
