ON Semiconductor MC74HC373ADWR2 Octal D-Type Latch

The MC74HC373ADWR2 is a high-performance, octal D-type latch integrated circuit from ON Semiconductor, designed to operate as a versatile memory device in a wide array of digital applications. This component is part of the HC family, which signifies the use of high-speed CMOS technology to achieve its operational characteristics.

With its 3-state non-inverting outputs, the MC74HC373ADWR2 is capable of driving 15 LSTTL loads, which makes it highly compatible with a variety of logic families. The octal D-type latch is designed to directly interface with the SPI and QSPI protocols, ensuring ease of integration into serially controlled systems and microprocessor-based applications.

The device comes in a wide-body SOIC-20 package, providing a compact footprint that is suitable for space-constrained designs. Its surface-mount design allows for efficient assembly on printed circuit boards, facilitating its use in high-volume manufacturing environments.

Key features of the MC74HC373ADWR2 include its high noise immunity, which is characteristic of CMOS technology, and low power consumption, a crucial aspect for battery-operated and power-sensitive applications. The latch operates over a broad voltage range from 2V to 6V, providing designers with the flexibility to use it in systems with varying power supply levels.

The MC74HC373ADWR2 also boasts a significant data retention capability with its transparent latch feature. The device allows data to flow from the input to the output when the latch enable (LE) input is high, and it retains the data when LE is low, even if the input changes. This feature is particularly useful in applications where data must be captured and held stable for subsequent processing or transfer.

Overall, the ON Semiconductor MC74HC373ADWR2 is a reliable and versatile choice for designers who require a high-quality octal D-type latch that combines performance, low power operation, and ease of use in a wide range of digital applications, from consumer electronics to industrial control systems.
