SN74HC590AD

Counter Dividers Overview

The SN74HC590AD is an 8-bit binary counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features synchronous up-counting with an asynchronous reset input. The device utilizes positive-edge triggering for its clock signal. It includes an 8-bit parallel output register equipped with three-state outputs, allowing direct interface with bus systems. The component is housed in a 16-pin SOIC surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Synchronous 8-bit binary counting mechanism with dedicated parallel output storage
• Three-state outputs on the register stage for efficient bus interfacing
• Asynchronous reset capability for immediate clearing of count states

Counter Dividers Applications

• Digital counting circuits requiring precise frequency division

Counter Dividers Procurement Notes

Verify the specific suffix against official documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status through current manufacturer notices. Ensure the source document matches the exact part number to avoid discrepancies in electrical characteristics or thermal ratings.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous counter with latched outputs is required. The HC series offers standard CMOS performance suitable for general-purpose digital logic. Consider the SOIC package constraints for PCB layout and verify that the operating voltage aligns with the system's power supply rails.

Counter Dividers Part Context

This device belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for sequential logic design. The SN74HC590A variant integrates both the counter and the output register into a single monolithic structure, simplifying circuit design compared to discrete solutions.
