STMicroelectronics 74LVX573TTR - Low Voltage Octal Latch with 3-STATE Outputs

The 74LVX573TTR is a high-speed CMOS octal latch manufactured by STMicroelectronics, designed for use in applications requiring the capture and retention of an 8-bit data set. With its advanced low-voltage silicon-gate technology, this device is particularly suitable for interfacing with 3.3V systems and is also tolerant to 5V inputs, making it versatile for mixed-voltage environments.

This integrated circuit features eight latches with 3-STATE standard outputs. The 3-STATE outputs allow for direct connection to a bus-organized system, facilitating ease of data flow and multiplexing. The octal latch is activated when the Latch Enable (LE) input is held high, allowing data on the inputs to be captured and held once the LE signal returns to a low state. Meanwhile, the Output Enable (OE) input controls the outputs, allowing the data to be presented to the connected bus when OE is low and isolating the bus when OE is high.

The 74LVX573TTR operates over a broad voltage range from 2.0V to 3.6V, providing low power consumption and reliable performance. Its fast propagation delay times and high noise immunity characteristics are in line with the requirements of high-speed memory interfacing, data acquisition systems, and communication control environments.

Encased in a TSSOP20 (Thin Shrink Small Outline Package) type package, the 74LVX573TTR is designed for surface-mount technology (SMT), ensuring a compact footprint on the PCB (Printed Circuit Board) and compatibility with automated assembly processes. This makes it an excellent choice for space-constrained applications that demand high-density electronic components.

Key features of the 74LVX573TTR include:

• Eight latches in a single package for efficient data handling
• 3-STATE outputs for easy bus connectivity
• Wide operating voltage range (2.0V to 3.6V) for flexible power design
• Input voltage level compatible with 5V systems
• Low power consumption for energy-efficient designs
• Fast propagation delays for high-speed operation
• High noise immunity
• Compact TSSOP20 packaging for space-saving applications

Overall, the STMicroelectronics 74LVX573TTR is a robust and reliable choice for designers looking to implement latching functions in their digital systems, particularly when operating within low-voltage parameters and requiring high-speed performance.
