ON Semiconductor MC74LCX74DTG Dual D-Type Positive Edge-Triggered Flip-Flop

The MC74LCX74DTG from ON Semiconductor is a high-performance, dual D-type positive edge-triggered flip-flop integrated circuit, designed to operate from a 2.3V to 3.6V power supply. This makes it ideal for interfacing with 3.3V logic levels in modern digital systems. The MC74LCX74DTG is part of the LCX family of products which are known for their low voltage operation and low power consumption.

Each flip-flop has independent DATA, SET, RESET, and CLOCK inputs with both Q and Q̅ outputs. This level of control provides the user with the flexibility needed for a variety of synchronous and asynchronous applications. The SET and RESET inputs are asynchronous, allowing for immediate setting or resetting of the flip-flop, which is particularly useful in initialization and emergency stop scenarios.

The MC74LCX74DTG utilizes advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation. This balance of speed and power efficiency is critical in today's battery-operated portable devices and low-power applications. Furthermore, the device is designed with an input hysteresis which allows for slower input transition signals and better noise immunity, enhancing the performance of the circuit in real-world noisy environments.

ON Semiconductor's MC74LCX74DTG is offered in a TSSOP-14 package, which is compact and suitable for space-constrained applications. The device also features the capability to drive 24 mA at the outputs, providing good signal integrity and driving capability.
