STMicroelectronics 74LCX374M Low Voltage Octal D-Type Flip-Flop

The 74LCX374M is a high-performance, low-voltage octal D-type flip-flop with a clear function from STMicroelectronics. Designed for use in 3.3V VCC operating systems, this device is particularly suitable for interfacing with 5V systems, providing a robust solution for bi-directional level translation in mixed 3.3V/5V systems.

This flip-flop features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The common buffered clock (CP) and a master reset (MR) input control all flip-flops. The MR input has an internal pull-up resistor, allowing for ease of use as the reset can be left floating for normal device operation. When the MR is taken low, all flip-flops are simultaneously cleared to the low state.

The 74LCX374M is characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of industrial applications. The device comes in a 20-lead SOIC package, which is compact and suitable for space-constrained applications. With its bus-hold data inputs, the 74LCX374M eliminates the need for external pull-up or pull-down resistors, simplifying circuit design and reducing board space.

Key features include:

• 5V tolerant inputs and outputs for interfacing with 5V logic levels
• 2.3V to 3.6V VCC specifications provided
• High drive capability: ±24mA at the outputs
• Power down high impedance inputs and outputs
• Supports live insertion and withdrawal (partial power-down mode)
• Bus-hold data inputs eliminate the need for external pull-up/pull-down resistors
• Lead-free, RoHS-compliant, and 100% tested for quiescent current at 20V

With its low power consumption and fast propagation delay, the 74LCX374M is an excellent choice for use in power-sensitive and timing-critical applications, such as telecommunications, computing, and high-speed data processing systems. STMicroelectronics' commitment to quality ensures that this flip-flop meets the highest standards of performance and reliability.

The 74LCX374M is part of STMicroelectronics' LCX family, which is known for its high-performance, low-voltage, and low-power operation, making it a versatile component for modern digital systems.
