SN74HC590ANE4

Counter Dividers Overview

The SN74HC590ANE4 is an 8-bit binary counter with a storage register, manufactured by Texas Instruments in the HC logic series. It operates on a 2 V to 6 V supply voltage and features high-current 3-state parallel outputs capable of driving up to 15 LSTTL loads. The device includes separate clocks for the counter and register, direct clear functionality, and a ripple-carry output for cascading. Packaged in a 16-pin PDIP through-hole format, it supports an operating temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Contains an 8-bit binary counter feeding an 8-bit storage register with parallel outputs
• Features high-current 3-state outputs for bus-driven applications
• Includes direct clear input and count-enable inputs for precise control
• Provides a ripple-carry output to facilitate easy cascading of multiple stages

Counter Dividers Applications

• Digital counting systems requiring latched output states
• Bus-driven data acquisition circuits
• Cascaded timing and sequencing logic designs

Counter Dividers Procurement Notes

Verify that the ordering suffix E4 confirms RoHS compliance and lead-free status as per Texas Instruments standards. Confirm the package type matches the required PCB footprint for the 16-pin PDIP configuration. Ensure the operating temperature range meets the specific environmental requirements of the target application before finalizing procurement.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous binary counter with latching capability is required within the HC logic family. It is suitable for designs needing 3-state outputs to interface with shared buses. Consider the 2 V to 6 V supply range and the specific timing characteristics relative to system clock speeds. Verify compatibility with existing logic levels if interfacing with other families.

Counter Dividers Part Context

This part belongs to the SN74HC590A series, which integrates an 8-bit counter and register. The 'E4' suffix denotes environmental compliance, specifically RoHS and lead-free manufacturing. It is a catalog version of the device, distinct from military or specialized variants. The device is designed for general-purpose digital logic applications requiring reliable binary counting and data storage.

Counter Dividers Replacement Considerations

SN74HC590AN is the manufacturer-recommended equivalent without the E4 suffix.
