Product Overview: 74HCT563DB,118

The 74HCT563DB,118 is a high-quality integrated circuit from NXP Semiconductors, designed for a wide range of electronic applications. This particular chip is a member of the 74HCT series, which is well-known for its high-speed CMOS technology. The device is specifically tailored to operate at the same high speed as LSTTL (Low-power Schottky Transistor-Transistor Logic), while maintaining the CMOS low power dissipation.

The 74HCT563DB,118 is an octal D-type transparent latch with 3-state outputs. It features eight latches with three-state outputs for bus oriented applications. The device is capable of storing eight bits of data when the latch enable (LE) input is high, and holding that data when LE is low. When the output enable (OE) input is low, the eight outputs are active and reflect the data that is set at the latches. However, when OE is high, the outputs go into a high-impedance state, which effectively disconnects them from the bus. This high-impedance state is essential for bus-driven systems and allows for multiple devices to share the same bus lines without interference.

Manufactured in a DB package, the 74HCT563DB,118 is a surface-mount device and is supplied in a 20-pin SSOP (Shrink Small Outline Package) which is ideal for space-constrained applications. This package type ensures a minimal footprint on the PCB while providing robust performance. The device operates over a wide temperature range and has a balanced propagation delay and transition times, which is crucial for maintaining signal integrity in high-speed digital circuits.

With its compatibility with TTL levels, the 74HCT563DB,118 can be used in mixed-technology environments and can interface with both CMOS and LSTTL logic levels without the need for any additional interfacing components. This feature simplifies design and reduces overall system cost.

The 74HCT563DB,118 is suitable for a variety of digital applications, including computers, data storage, communication devices, and complex industrial control systems. Its reliability and performance make it an excellent choice for designers looking for a dependable solution for their digital logic requirements.

In summary, the 74HCT563DB,118 from NXP Semiconductors is a versatile and efficient octal D-type latch that is perfect for use in systems that require high-speed operation, low power consumption, and the ability to drive bus lines without compromising performance.
