STMicroelectronics 74LVQ374TTR Octal D-Type Flip-Flop
The 74LVQ374TTR is a high-performance, low-voltage CMOS octal D-type flip-flop with 3-state outputs, manufactured by STMicroelectronics. This integrated circuit is designed for use in applications requiring the capture and storage of data in a digital system. The product is part of the 74LVQ family, which is known for its low-voltage operation and high-speed performance.
The 74LVQ374TTR features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The flip-flops capture the state of their respective D inputs at the rising edge of the clock input, and this state is held at the Q outputs until the next rising edge. The use of a master-slave design ensures that the outputs change state synchronously with the clock signal, minimizing the risk of data glitches and setup/hold violations.
In addition to the standard flip-flop functionality, the 74LVQ374TTR includes a direct clear input, which can be used to reset all flip-flops simultaneously, ensuring that the Q outputs can be quickly set to a known state when needed. The device also features 3-state outputs, which can be placed in a high-impedance state, allowing for bus-oriented applications where multiple outputs need to share a common connection.
Operating at a voltage range of 2.5V to 3.3V, the 74LVQ374TTR is particularly suitable for interfacing with 3.3V logic devices while maintaining compatibility with 5V systems. The low power consumption of this device makes it ideal for battery-operated equipment, and its high-speed performance is well-suited for high-frequency data processing applications.
The device is available in a TSSOP20 package, which is a space-saving option for PCB design, and its lead-free and RoHS-compliant construction makes it an environmentally friendly choice for modern electronic systems. The 74LVQ374TTR's combination of features makes it a versatile component for a wide range of digital applications, including computers, communication devices, and advanced microprocessor systems.
