TC74HC590AP(F)

Overview

The TC74HC590AP(F) is an 8-bit binary counter with output registers manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2V to 6V and features through-hole mounting in a 16-DIP package. The device supports positive edge triggering and includes dedicated clock inputs for both the counter and register stages. It is RoHS3 compliant and designed for general-purpose digital logic applications requiring stable data storage and counting functions.

Feature Summary

• Integrates an 8-bit binary counter with separate output registers for data latching
• Supports positive edge-triggered operation for precise timing control
• Provides independent clock inputs for counter and register sections

Applications

• Digital counting systems requiring data retention
• Timing sequence generation circuits
• General-purpose logic interfacing

Procurement Notes

Verify component authenticity against Toshiba Semiconductor and Storage specifications. Confirm package type matches 16-DIP requirements. Ensure operating conditions align with the specified voltage and temperature ranges. Check for obsolete status indicators as availability may be limited compared to active series components.

Selection Notes

Select this component when an 8-bit counter with output registration is required. Ensure the design accommodates the 16-pin DIP footprint. Verify that the input signal levels are compatible with the HC logic family thresholds. Consider the propagation delay characteristics if high-speed performance is critical for the application timeline.

Part Context

This part belongs to the 74HC series of CMOS logic devices, known for wide voltage operation and compatibility with standard TTL logic levels. The TC74HC590 variant specifically addresses applications needing both counting and temporary data storage capabilities within a single integrated circuit package.

Replacement Considerations

SN74HC590AN is listed as a similar substitute option. Verify pinout compatibility and electrical parameters before substitution.
