Product Overview: CD74HCT563M from Texas Instruments

The CD74HCT563M is a high-performance, CMOS logic-level Octal D-Type Transparent Latch designed and manufactured by the industry-leading semiconductor company, Texas Instruments. This integrated circuit is part of the HCT family, which signifies that it is compatible with both TTL and CMOS logic levels, offering a versatile solution for various digital applications.

The device features eight latches with three-state outputs for bus-organized systems applications. Each latch is transparent, meaning that when the latch enable (LE) input is high, the Q outputs follow the data (D) inputs. However, when LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs before the drop of LE.

The CD74HCT563M also includes an output enable (OE) feature, which, when high, puts the outputs into a high-impedance state. This high-impedance state ensures that the outputs will neither load nor drive the bus lines significantly, and is ideal for interfacing with bus lines in a bus-organized system.

With its wide operating voltage range of 4.5V to 5.5V, the CD74HCT563M can easily integrate into 5V systems, providing a robust interface that is tolerant to voltage variations. The device also boasts a high noise immunity characteristic of CMOS devices, making it suitable for noisy environments.

Available in an SOIC (Small Outline Integrated Circuit) package, the CD74HCT563M offers a compact footprint and surface-mount technology compatibility, which is essential for modern, space-constrained electronic assemblies. The device operates over a broad temperature range, making it suitable for various industrial and commercial applications.

Whether used in data storage, communication systems, or computer servers, the CD74HCT563M from Texas Instruments delivers reliable performance and integration ease, making it an excellent choice for designers and engineers seeking a high-quality latch for their digital systems.
