ON Semiconductor MC74HC373ADWR Octal D-Type Latch

The ON Semiconductor MC74HC373ADWR is a high-performance, octal D-type latch that is designed for use in a wide variety of digital applications. This integrated circuit is part of the high-speed CMOS HC family and features a non-inverting 3-state bus interface. It is ideal for temporary storage of data and for transferring data from the input to the output, with the output only active when the latch-enable (LE) input is high.

The MC74HC373ADWR is packaged in a wide-body SOIC-20W package, ensuring a compact footprint while providing adequate thermal performance for typical applications. The device operates over a broad voltage range from 2V to 6V and offers a balanced propagation delay and transition times, providing reliable high-speed operation.

Key features of the MC74HC373ADWR include:

• Eight D-type latches: With 3-state outputs for bus-oriented applications.
• Wide operating voltage range: Compatible with 2V to 6V, making it suitable for various logic level requirements.
• Low power consumption: The typical low quiescent current of 80µA and low power dissipation make it appropriate for battery-operated devices.
• High noise immunity: Characteristic of CMOS devices, providing robust performance in electrically noisy environments.
• Output drive capability: Capable of driving 15 LSTTL loads, which ensures compatibility with older logic families.
• Pin and function compatible: With standard LS logic counterparts, allowing for easy integration or replacement in existing designs.

The device's multiple inputs and outputs are buffered to lower the drive requirements, which further reduces the power consumption. Additionally, the MC74HC373ADWR is characterized for operation from -55°C to 125°C, making it a reliable choice for industrial and automotive applications that demand high reliability and extended temperature ranges.

Whether you're designing data storage, multiplexing, or other digital logic applications, the ON Semiconductor MC74HC373ADWR offers a versatile and efficient solution. Its combination of high-speed performance, low power consumption, and robust noise immunity ensures that it can meet the requirements of the most demanding digital systems.
