Overview of SN74AHCT573DBR from Texas Instruments

The SN74AHCT573DBR is a high-performance, octal transparent D-type latch designed by Texas Instruments, one of the leading manufacturers in the semiconductor industry. This integrated circuit is part of the AHCT family, which is known for its advanced high-speed CMOS technology. The device is particularly suitable for applications requiring the capture and storage of data with the capability to provide output only when desired.

Key Features

• Logic Type: Octal Transparent D-type Latches
• Logic Family: AHCT
• Output Type: 3-State
• Number of Channels: 8
• Supply Voltage: 4.5V to 5.5V
• Operating Temperature: -40°C to 85°C
• Package: SSOP (Shrink Small-Outline Package) with 20 pins
• RoHS: Compliant

Functionality

The SN74AHCT573DBR features eight D-type latches with 3-state outputs. Each latch is transparent; that is, while the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs. A 3-state output enables the device to be used in bus-oriented applications, allowing multiple outputs to connect to a bus without conflict.

Applications

With its fast propagation delay and edge-rate control features, the SN74AHCT573DBR is ideal for interfacing with bus lines in a system. It is widely used in:

• Data storage and retrieval systems
• Communication systems
• Microprocessor or microcontroller interface
• Buffer memory address registers

Quality and Reliability

As with all Texas Instruments products, the SN74AHCT573DBR is manufactured to high standards of quality and reliability. It is designed to meet the rigorous demands of the modern electronic environment. The device is also RoHS compliant, ensuring that it meets the latest environmental standards and regulations.
