Product Overview: 74HC374DB from NXP
The 74HC374DB is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, a leader in the electronics industry, the product is part of the 74HC family which is renowned for its robustness and high performance. This particular integrated circuit is designed to provide the functionality of an octal D-type flip-flop with 3-state outputs.
The 74HC374DB features eight edge-triggered, D-type flip-flops with individual D inputs and O outputs. The common clock (CP) and master reset (MR) inputs control all flip-flops. The device operates by transferring the data present at a D-input to the corresponding O-output during the rising edge of the clock pulse. The MR input can override the clock and clear all flip-flops simultaneously when taken low.
One of the key attributes of the 74HC374DB is the 3-state output control. This allows for direct connection to a bus-organized system. When the output enable (OE) input is high, the outputs are in a high-impedance state, which effectively disconnects them from the bus. This feature is crucial for bus-driven applications, allowing multiple devices to share the same bus lines without interference.
Designed to operate from a wide range of power supplies, the 74HC374DB can function with a supply voltage ranging from 2.0 to 6.0 V. This flexibility in voltage makes the device suitable for interfacing with both TTL and CMOS logic levels. Additionally, the low power consumption and balanced propagation delays ensure that the device is suitable for high-speed operation in a variety of applications.
Encased in a slimline 20-pin plastic SSOP package, the 74HC374DB is optimized for reduced space and weight, which is particularly advantageous for modern compact electronic assemblies. Its small form factor and low power dissipation make it an excellent choice for use in microprocessor or microcontroller-based systems, including computers, data storage, and communication devices.
Overall, the 74HC374DB from NXP is a versatile and reliable component that provides the essential features needed for secure data storage and transfer within digital systems.
