STMicroelectronics M74HC374B1R Octal D-Type Flip-Flop

The STMicroelectronics M74HC374B1R is a high-speed CMOS octal D-type flip-flop integrated circuit, designed to meet the stringent requirements of modern digital systems. This device is part of the HC family, which signifies a high-speed CMOS technology, offering a perfect balance between speed and power consumption, making it an ideal choice for a wide range of applications.

The M74HC374B1R features eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The integrated circuit is designed to be used as temporary storage for binary information, transferring data from the input to the output upon a clock transition from low to high (positive-edge trigger).

The true outputs of the flip-flops can enter a high impedance state (off state) by applying a high logic level to the Output Enable (OE) input, which makes this device particularly suitable for interfacing with bus-oriented systems where multiple drivers can share the same line. This bus-friendly feature allows for the direct connection of the outputs to the bus line without the need for external pull-up resistors.

Key features of the M74HC374B1R include:

• High-speed operation: Ensuring swift data transfer and processing, suitable for high-performance systems.
• Low power dissipation: Offering energy efficiency, which is crucial for battery-powered and energy-sensitive applications.
• Wide operating voltage range: Compatible with a variety of system voltages, increasing the flexibility of system design.
• Pin and function compatible with 74 series: Allowing easy integration or replacement in existing designs that use the industry-standard 74 series logic circuits.
• Latch-up performance exceeds 500mA: Providing robustness against over-current conditions and ensuring the reliability of the device.
• ESD protection: Ensuring the device is safeguarded against electrostatic discharge events, which enhances its durability and longevity.

Available in a DIP20 package, the M74HC374B1R is designed for use in a broad range of applications, including memory address latching, data storage, multiplexed data transmission, and other situations where a temporary data buffer is required. With its high-speed performance and low power consumption, the M74HC374B1R from STMicroelectronics is an excellent choice for designers looking to implement reliable and efficient data handling in their digital systems.
