STMicroelectronics 74LVQ174TTR Hex D-Type Flip-Flop

The 74LVQ174TTR from STMicroelectronics is a high-performance, low-voltage CMOS Hex D-Type Flip-Flop with clear. This advanced technology device is designed to operate from a 2.5V to 3.6V power supply, making it ideal for use in battery-operated systems and portable electronics. The 74LVQ174TTR is particularly suitable for the implementation of buffer registers, I/O ports, bidirectional bus drivers, and working registers.

With its fast propagation delays and high noise immunity characteristic of CMOS devices, the 74LVQ174TTR ensures reliable operation in a variety of demanding applications. The device features six edge-triggered flip-flops with individual D inputs and Q outputs. The clear input has a dedicated pin that, when taken to a high logic level, resets all six flip-flops, ensuring the Q outputs are in a low state.

The 74LVQ174TTR is available in a TSSOP package, which is designed to offer a reduced footprint on the PCB and is suitable for space-constrained applications. The package is also optimized for improved thermal performance and lower power consumption. With its wide operating temperature range, the device is reliable in various environmental conditions, making it a versatile choice for industrial and commercial markets.
