ON Semiconductor MC74AC573MELG Product Overview

The MC74AC573MELG from ON Semiconductor is a high-performance, octal transparent latch with 3-state outputs designed for 2-V to 6-V VCC operation. This integrated circuit is ideal for use in applications that require the temporary storage of information. It features eight latches with three-state versions of the D-type flip-flop. The transparent latches allow data to flow from the input to the output when the latch-enable (LE) input is HIGH, and latch the data when LE is LOW.

Constructed with advanced CMOS logic technology, the MC74AC573MELG provides a robust and reliable solution for digital systems. It offers a significant advantage in terms of speed, with propagation delay times significantly less than those of its bipolar equivalents while maintaining CMOS low power consumption. The device is capable of driving 24 mA at the outputs, allowing for direct drive of data buses in microprocessor and microcontroller-based systems.

The octal transparent latch is housed in a 20-lead SOIC package, which is a surface-mount device designed for space-saving on PCBs. Its compact footprint and low profile make it suitable for use in densely populated boards where real estate is at a premium. The MC74AC573MELG is also characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions.

Key features of the MC74AC573MELG include:

• Eight latches in a single package.
• 3-state outputs for bus-oriented applications.
• Output capability: Standard.
• ICC category: Latches.
• Supports live insertion and withdrawal (Note 1).

ON Semiconductor's MC74AC573MELG is a versatile component that can be used in a multitude of digital applications. It is especially useful in the temporary storage of data, acting as an interface between two different systems or buses, and providing a holding register for data manipulation. With its high-speed performance and low power consumption, this device is an excellent choice for modern electronic designs.
