M74HC590TTR

Counter Dividers Overview

The M74HC590TTR is an 8-bit binary counter register with 3-state outputs manufactured by STMicroelectronics. It integrates an 8-bit binary counter feeding an 8-bit storage register, both featuring positive edge triggering. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 61 MHz at 6V. It includes separate clocks for the counter and register, a ripple carry output (RCO) for cascading, and inputs for direct clear and count enable.

Counter Dividers Feature Summary

• Integrates an 8-bit binary counter and an 8-bit storage register with parallel outputs
• Features 3-state outputs controlled by a dedicated output enable input
• Includes a ripple carry output (RCO) to facilitate easy cascading of multiple devices
• Provides separate positive edge-triggered clocks for the counter and the storage register

Counter Dividers Applications

• Cascaded counting systems utilizing the ripple carry output
• Digital data storage applications requiring parallel output access
• High-speed logic circuits operating within wide voltage ranges

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels as this part number is marked obsolete in distributor databases. Confirm package integrity upon receipt, specifically checking for TSSOP-16 pin alignment. Review current datasheet revisions to ensure compatibility with existing design specifications before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when an integrated solution combining counting and latching functions is required. It is suitable for designs needing independent control over counting and storage operations via separate clock inputs. Consider the 3-state output capability if bus sharing or high-impedance states are necessary for system architecture.

Counter Dividers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with standard 74 series 590 logic families. The TTR suffix indicates it is supplied in tape and reel packaging, designed for automated surface-mount assembly processes on printed circuit boards.

Counter Dividers Replacement Considerations

Nexperia USA Inc. offers the 74HC590PW,118 as a direct substitute. Verify pinout and electrical characteristics against the original datasheet to ensure seamless integration into existing hardware designs without modification.
