STMicroelectronics 74LVX174TTR Hex D-Type Flip-Flop with Clear

The 74LVX174TTR from STMicroelectronics is a high-speed CMOS hex D-type flip-flop integrated circuit, which comes in a space-saving TSSOP20 package. This advanced flip-flop is designed to support the stringent requirements of high-speed memory decoders and data transmission systems. With its low-voltage operation and power-down high-impedance inputs and outputs, it is optimized for 3.3V power supply systems, but it can also operate with a 5V supply, making it versatile for various digital logic applications.

The device features six D-type flip-flops with direct clear inputs. Each flip-flop has an individual clear input (CLR) and a data input (D), as well as a single clock input (CK). When the clock input is triggered, the value on the data input is transferred to the flip-flop's output (Q) on the rising edge, providing synchronous data transfer. The clear input, when taken low, resets the output to a low state regardless of the other inputs, ensuring a predictable initialization state for all flip-flops within the device.

Key attributes of the 74LVX174TTR include its low power dissipation, characterized by a low quiescent current (ICC) and low dynamic power (CPD). This makes it an excellent choice for battery-powered and portable applications where power efficiency is critical. Furthermore, the device boasts high noise immunity and the ability to drive 24mA loads, which is beneficial for driving heavier loads in a system or for interfacing with other logic families.

For design flexibility, the 74LVX174TTR is fully compatible with the 74 series logic family, and it can be easily integrated into existing designs that require the speed and power characteristics of the LVX family. The device is also characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of environmental conditions.

In summary, the STMicroelectronics 74LVX174TTR is a robust and reliable component suitable for a variety of digital applications, including data storage, communication, and industrial systems, where high-speed, low-power operation is a necessity.
