SN74ACT534DBRG4 Octal D-Type Flip-Flop by Texas Instruments

The SN74ACT534DBRG4 from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop with a clear function, designed to be used in a wide array of digital applications. This integrated circuit (IC) is part of the 74ACT series, which is known for its high-speed CMOS logic operating with the advantage of advanced CMOS technology.

Key Features

• Logic Type: The device features eight D-type flip-flops with 3-state outputs.
• Edge-Triggered Design: Each flip-flop is edge-triggered, responding to the rising edge of the clock input signal, ensuring precise timing control for digital data processing.
• Clear Function: A clear input is provided, which when taken low, immediately sets all outputs to a low state, regardless of the clock input, enabling the synchronous reset of connected systems.
• 3-State Outputs: The 3-state outputs allow for connection to a bus-oriented system, facilitating the sharing of bus lines without the need for external multiplexers.
• High-Drive Outputs: The IC can drive up to 24mA at the outputs, providing good drive capabilities for various digital loads.
• Wide Operating Voltage: It operates over a broad voltage range of 4.5V to 5.5V, making it suitable for interfacing with both 5V TTL and CMOS digital systems.

Applications

The SN74ACT534DBRG4 is versatile and can be employed in numerous applications, such as temporary data storage, data transfer, data manipulation, and as a buffer or interface between two different subsystems within a digital circuit. Its robust design and 3-state outputs make it particularly useful in bus-oriented systems where multiple devices share a common data bus.

Package and Quality

This device comes in a DBRG4 package, which is a 20-pin SSOP (Shrink Small Outline Package) that offers a reduced footprint on printed circuit boards (PCBs) compared to standard dual in-line packages. Texas Instruments ensures that the SN74ACT534DBRG4 meets stringent quality standards, providing reliable and consistent performance for critical digital applications.
