STMicroelectronics 74LVX574MTR - Low Voltage Octal D-Type Flip-Flop

The 74LVX574MTR is a high-speed, low-power octal flip-flop with a bus interface capability designed for 3.3V VCC operation. Manufactured by STMicroelectronics, this device is part of the 74LVX family, which is known for its low voltage support and compatibility with TTL levels. The 74LVX574MTR is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

With its advanced 0.5µm CMOS technology, the 74LVX574MTR offers a robust solution for applications that require high-speed data storage and transfer while maintaining low power consumption. Each flip-flop features a separate D-type input and a Q output. The data on the D input is transferred to the Q output on the positive-going edge of the clock pulse. The device also includes an output enable (OE) and a clear (CLR) input, which are used to control the output states and reset the flip-flops respectively.

Key features of the 74LVX574MTR include:

• Optimized for Low Operating Voltage: 2.7V to 3.6V
• High-Speed Operation: tPD = 3.8ns (max) at 3.3V
• Power Down Protection on Inputs and Outputs
• Low Quiescent Current: 20µA (max)
• Supports Live Insertion and Withdrawal (I<sub>OFF Specification)
• 5V Tolerant Inputs and Outputs
• Lead-Free, Halogen-Free, and RoHS Compliant

The device comes in a TSSOP20 package, which is a space-saving option for PCB design, allowing for more compact electronic designs. The 74LVX574MTR is ideal for interfacing with 5V systems and can be used in a variety of digital applications, including computers, communication devices, and embedded systems, where low power operation is essential.

With its combination of high-speed performance, low voltage operation, and advanced features, the STMicroelectronics 74LVX574MTR is a reliable and efficient choice for modern electronic applications that require octal D-type flip-flops.
