N74ALS573BD Octal Transparent Latch by NXP

The N74ALS573BD is a high-performance integrated circuit designed by NXP Semiconductors, renowned for its commitment to innovation and quality in the electronics industry. This octal transparent latch is part of the Advanced Low-Power Schottky (ALS) family, which is designed to offer both speed and energy efficiency in digital systems.

Key Features

• Octal D-Type Latches: With eight latches in one package, the N74ALS573BD provides a convenient way to store data bits with its D-type flip-flop structure.
• Transparent Mode: The latches are transparent, meaning that when the latch enable (LE) input is high, the Q outputs will follow the D inputs directly, allowing for real-time tracking of input changes.
• Output Control: The device includes an Output Enable (OE) feature that allows the user to place the eight outputs in either a normal logic state or a high-impedance state, facilitating the connection to a bus-structured system.
• Edge-Triggered Latching: The transition of the LE input from high to low latches the input data at the D inputs, ensuring stable data storage.
• Low Power Consumption: As part of the ALS series, this device is optimized for low power consumption without compromising speed, making it suitable for power-sensitive applications.
• Wide Operating Temperature Range: The N74ALS573BD is designed to operate over a broad temperature range, ensuring reliability across various environmental conditions.

Applications

The N74ALS573BD is versatile and can be used in a wide range of applications, including:

• Temporary storage for data synchronization
• Interface between mismatched bus speeds
• System resource sharing
• Support for bus-oriented systems

Technical Specifications

With a 20-pin package, the N74ALS573BD is designed to interface directly with 16-bit data buses. It supports a voltage range typically between 4.5V and 5.5V, making it compatible with TTL logic levels. The device also features fast propagation delays and setup times, contributing to its high-speed operation.

In summary, the N74ALS573BD from NXP is a reliable and efficient solution for designers who require octal transparent latches with high-speed performance and low power consumption.
