ON Semiconductor MC74ACT373DWR2 Octal Transparent Latch

The MC74ACT373DWR2 is a high-performance, octal transparent latch designed and manufactured by ON Semiconductor, a leading provider of semiconductor-based solutions. This integrated circuit is part of the ACT series, which is well-known for its high-speed operation and compatibility with TTL (Transistor-Transistor Logic) levels. The device is specifically designed to store and hold the data presented to its inputs, providing a stable output even when the input signals are no longer present.

This octal latch features eight latches with three-state outputs for bus-oriented applications. The MC74ACT373DWR2 operates with an extended voltage range of 4.5V to 5.5V, making it suitable for interfacing with 5V logic systems. The device is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

The MC74ACT373DWR2 comes in a 20-lead SOIC wide body package, which is designed for optimal space-saving on PCBs (Printed Circuit Boards). The wide body package also aids in heat dissipation, which is crucial for maintaining the integrity and longevity of the device in various applications.

Key features of the MC74ACT373DWR2 include:

• Eight latches in a single package for efficient use of board space.
• Transparent latches which allow data to flow through when the latch enable (LE) input is high.
• Three-state outputs that can be set high, low, or high impedance, providing flexibility in bus-oriented applications.
• Output control (OC) and latch enable (LE) inputs for precise control of the data flow.
• Edge-triggered latching action that captures data on the rising edge of the clock signal.
• High noise immunity characteristic of CMOS devices, ensuring stable operation in electrically noisy environments.

The MC74ACT373DWR2 is ideal for use in a variety of applications, including memory address latching, data storage, and buffer memory for processors. Its ability to maintain the integrity of data during transient conditions makes it an essential component in digital systems that require stable and reliable data handling capabilities.

Overall, the MC74ACT373DWR2 from ON Semiconductor is a versatile and reliable choice for designers and engineers looking to implement an octal transparent latch in their digital systems.
