Product Overview: 74HCT573DB from NXP Semiconductors

The 74HCT573DB is a high-speed Si-gate CMOS device from NXP Semiconductors, renowned for its robust performance and compatibility with Low-power Schottky TTL (LSTTL). It is part of the 74HCT family, which is designed to operate at the same speed as 74LS circuits but with the lower power consumption characteristic of CMOS technology.

This octal D-type transparent latch features 3-state outputs, making it an ideal choice for interfacing with bus-oriented systems. The 74HCT573DB consists of eight D-type latches with 3-state true outputs. The device is particularly useful in applications where the bus lines need to be controlled effectively, allowing for data flow to be managed with precision.

Key Features:

• Logic Type: Octal D-type transparent latch with 3-state outputs.
• Operating Voltage: A range of 4.5V to 5.5V, making it compatible with TTL power supply levels.
• High-Speed Performance: Ensures quick data transfer and processing with a typical propagation delay of 15 ns.
• Power Consumption: Low power dissipation with a typical I_CC of 4 μA.
• Input Level: The device has TTL input levels for compatibility with various logic families.
• Package: Offered in a SSOP48 package, which is suitable for space-constrained applications.

Applications:

The 74HCT573DB is versatile and suitable for a wide range of applications, including:

• Bus driver interfaces
• Buffer memory address registers
• Control systems
• Data storage and retrieval systems

With its ability to latch 8 bits of data and then output them only when required, controlled by the output enable pin, the 74HCT573DB is a critical component in systems that require stable and reliable data handling. Its 3-state outputs also allow for direct connection to a bus, providing both high impedance and active driving states.

Overall, the 74HCT573DB from NXP Semiconductors is a high-quality, reliable choice for designers who need a latch that delivers both performance and power efficiency in a compact form factor.
