74ACT11590DW

Counter Dividers Overview

The SN74ACT11590DW is an octal binary counter with registered three-state outputs manufactured by Texas Instruments. It belongs to the 74ACT logic family, utilizing CMOS technology for low power consumption and high-speed operation. The device features asynchronous reset functionality and positive-edge triggering for reliable data latching. Designed for surface-mount applications, it operates within a supply voltage range of 4.5 V to 5.5 V. The component supports a maximum count rate of 80 MHz and exhibits a propagation delay of approximately 8 ns under standard test conditions.

Counter Dividers Feature Summary

• Octal binary counting architecture with registered outputs
• Asynchronous reset capability for immediate state clearing
• Three-state output drivers for bus line driving
• Positive-edge triggered clocking mechanism

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation modules
• Address decoding networks in embedded systems

Counter Dividers Procurement Notes

Verify the complete manufacturer part number, including the 'SN' prefix if required by specific design documentation, as datasheets may list both SN74ACT11590 and 74ACT11590 variants. Confirm the package suffix 'DW' corresponds to the SOIC-20 form factor required for your PCB footprint. Ensure the operating temperature grade matches your environmental specifications, as industrial grades may have different suffixes or availability. Cross-reference the specific revision level against your schematic to guarantee pinout compatibility.

Counter Dividers Selection Notes

Select this component when an octal counter with tri-state outputs is required for 5V logic systems. The ACT series offers superior speed compared to standard 74LS counterparts while maintaining compatible pinouts. Consider the 80 MHz count rate limit for high-frequency applications. Verify that the input voltage levels align with your system's logic thresholds. The SOIC-20 package is suitable for automated assembly processes requiring surface-mount technology.

Counter Dividers Part Context

This device is part of Texas Instruments' extensive 74ACT logic portfolio, designed to replace older 74LS and 74HC series components in high-performance designs. The ACT series bridges the gap between low-power HC technology and high-speed AC technology. It is widely used in telecommunications and computing equipment where moderate speed and low power are critical. The octal configuration reduces board space by integrating eight flip-flops into a single package.

Counter Dividers Replacement Considerations

Direct substitutes include the SN74ACT11590DR (tape and reel version) and other 74ACT11590 variants from Texas Instruments. Check for equivalent parts from other manufacturers such as ON Semiconductor or NXP, ensuring they match the 74ACT specification and SOIC-20 package. Verify that any alternative maintains the same asynchronous reset function and three-state output characteristics.
