ON Semiconductor MC74LCX74DR2G

The ON Semiconductor MC74LCX74DR2G is a versatile, high-performance dual D-type flip-flop integrated circuit designed to operate from a 2.3V to 3.6V power supply, making it ideal for low-voltage applications. This device is part of the LCX family, which is known for its low-voltage operation and low static power consumption. The MC74LCX74DR2G is particularly well-suited for interfacing with 5V systems, providing a bridge to newer technology nodes that require lower operating voltages.

Each flip-flop has individual clear and set inputs, as well as a clock (CLK) input. The outputs Q and Q̅ are available for each flip-flop, providing both the true and complemented outputs. The clear and set are asynchronous inputs that override the clock, allowing for immediate changes in the output state without waiting for a clock transition. This feature is critical for initializing or resetting digital circuits that require a known start state.

The MC74LCX74DR2G boasts advanced silicon-gate CMOS technology, which ensures that the device has reduced power dissipation, high noise immunity, and the ability to drive large capacitive loads with minimal additional power consumption. This technology also provides for a robust latch-up performance, which is crucial for maintaining the integrity of digital signals under transient conditions.

ON Semiconductor has packaged the MC74LCX74DR2G in a space-saving SOIC-14 package, making it an excellent choice for space-constrained applications. Its compact form factor is complemented by its industrial-grade temperature range, allowing it to operate reliably in a variety of environmental conditions.

The device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. This feature is essential for battery-powered devices where preserving power is crucial.

In summary, the ON Semiconductor MC74LCX74DR2G is a highly reliable and efficient solution for digital systems requiring low-voltage operation and high-speed performance. Its dual flip-flop design, low power consumption, and robust feature set make it a smart choice for designers looking to optimize their digital circuitry in a variety of applications.
