ON Semiconductor MC74LCX374DTR2 Octal D-Type Flip-Flop

The MC74LCX374DTR2 from ON Semiconductor is a high-performance, octal D-type flip-flop with a clear function. Designed for use in applications requiring a high-speed, low-power device, this flip-flop is part of the LCX family, which is known for its 5V tolerant inputs and outputs, allowing interface capability with 5V TTL logic.

This integrated circuit (IC) features eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The clear (CLR) input affects all flip-flops simultaneously and when taken low, it resets all the outputs to a low state, making it an ideal choice for initializing a system upon power-up or during a reset condition.

The MC74LCX374DTR2 operates over a broad voltage range of 2.3V to 3.6V and provides a 24-lead TSSOP package, ensuring a compact footprint on printed circuit boards. It is characterized for operation from -40°C to +85°C, making it suitable for industrial and automotive applications that require robust performance under varying environmental conditions.

With its low static and dynamic power consumption, the MC74LCX374DTR2 is optimal for power-sensitive designs. The device also supports live insertion and withdrawal (hot insertion) due to its bus-hold circuitry, which eliminates the need for external pull-up resistors and helps to prevent data corruption during the live insertion process.

Key features of the MC74LCX374DTR2 include:

• High-speed operation: tPD 4.5 ns (max) at 3.3V
• Low power dissipation: ICC 4 µA (max) at TA = 25°C
• Power down high impedance inputs and outputs
• ±24 mA output drive at 3.3V
• Supports 5V tolerant inputs and outputs
• Pb-Free, Halogen-Free, and RoHS compliant

The MC74LCX374DTR2 is well-suited for a variety of digital applications where low-voltage operation with 5V tolerant interface is essential. Its robust design and versatile features make it an excellent choice for designers looking to implement reliable data storage elements in their systems.
