Product Overview: 74HC374 Octal D-type Flip-Flop from NXP

The 74HC374 is a high-speed Si-gate CMOS device from NXP Semiconductors designed to deliver the functionality of the 74HC logic family with the added feature of an octal D-type flip-flop with 3-state outputs. This integrated circuit is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Key Features

• Logic Type: Octal D-type flip-flop with 3-state outputs
• High-Speed Performance: The 74HC374 offers fast propagation delays and high noise immunity characteristic of CMOS devices, making it ideal for high-speed applications.
• Wide Operating Voltage Range: It operates on a wide voltage range from 2V to 6V, providing compatibility with TTL levels and making it suitable for use in mixed-voltage systems.
• Low Power Consumption: Its low power consumption makes it an excellent choice for battery-operated and power-sensitive applications.
• Output Capability: The 74HC374 can drive up to 15 LSTTL loads, providing ample current for interfacing with most logic types.
• 3-State Outputs: The outputs can be placed in a high-impedance state, allowing for use in bus-oriented systems.

Applications

The 74HC374 is versatile and can be used in a variety of applications, including:

• Buffer registers
• I/O ports for microprocessors
• Bidirectional bus drivers
• Working registers
• Control registers

Product Specifications

The device features eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. The 3-state outputs are controlled by the output enable input (OE). A LOW on OE causes the outputs to assume a transparent state, while a HIGH on OE puts the outputs in the high-impedance state, allowing for bus-oriented applications.

With its robust design and wide operating voltage range, the 74HC374 from NXP is a reliable and efficient solution for your digital logic needs, ensuring high-speed operation and integration flexibility in your circuit designs.
