TC74HC592APF

Overview

The TC74HC592APF is an 8-bit binary counter and shift register integrated circuit manufactured by Toshiba Semiconductor and Storage. It belongs to the 74HC logic family, utilizing CMOS technology for low power consumption and high noise immunity. The device features a serial-in/parallel-out configuration with a storage register, allowing data to be shifted in serially and then transferred in parallel. It operates within a standard voltage range typical for HC series devices and is housed in a 16-pin DIP package.

Feature Summary

• Combines an 8-bit serial-in/parallel-out shift register with an 8-bit D-type flip-flop storage register
• Features independent clock inputs for shift and storage operations to control data transfer timing
• Includes a serial output for cascading multiple units to expand bit capacity

Applications

• Serial-to-parallel data conversion in digital communication systems
• Display driver interfaces requiring sequential data loading
• General-purpose binary counting applications in embedded controllers

Procurement Notes

Verify component status carefully as this part number is listed as obsolete. Confirm availability of stock or last-time-buy options through authorized distributors. Ensure substitute components meet identical pinout and electrical specifications to maintain system compatibility without redesign.

Selection Notes

Select this component when an 8-bit shift register with parallel output is required in a design using HC logic levels. Consider the 16-DIP package for through-hole prototyping or legacy board maintenance. Evaluate alternative active parts if long-term supply stability is critical for production volumes.

Part Context

This IC is part of the broader 74HC series of high-speed CMOS logic devices produced by Toshiba. It serves as a specialized variant within the counters and dividers category, specifically designed for sequential logic operations. The device complements other logic gates and buffers in complex digital circuits requiring data manipulation and storage functions.

Replacement Considerations

The SN74HC590AN from Texas Instruments is identified as a similar substitute part number. Verify functional equivalence regarding pin configuration and electrical characteristics before implementation.
