TC74AC373P(F)

Overview

The TC74AC373P(F) is an octal transparent latch with three-state outputs manufactured by Toshiba Semiconductor and Storage. It belongs to the 74AC logic series, providing eight D-type latches in a single package. The device operates within a supply voltage range of 2V to 6V and supports through-hole mounting in a 20-pin DIP package. It features true output polarity and is designed for bus-organized system applications requiring high-speed data storage and transfer capabilities.

Feature Summary

• Provides eight independent D-type latches for parallel data storage
• Features three-state outputs to facilitate bus-driven architectures
• Maintains transparency when latch enable signal is active

Applications

• Bus-organized system data storage
• Parallel-to-serial conversion interfaces
• High-speed digital signal buffering

Procurement Notes

Verify the specific suffix designation against official Toshiba documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required operating temperature ranges for the intended application environment before integration into final designs.

Selection Notes

Select this component for applications requiring octal data latching with high-speed performance. Consider the 20-pin DIP package for prototyping or legacy board layouts. Verify that the AC series speed and drive current meet the load requirements of the connected circuitry.

Part Context

This part is part of the standard 74AC logic family, known for improved speed over earlier HC series devices while maintaining CMOS power efficiency. It serves as a fundamental building block for memory interface circuits and temporary data holding stages in complex digital systems.

Replacement Considerations

Compatible substitutes include SN74AC373N from Texas Instruments and 74HC373D from Toshiba, provided voltage levels and package types align with the existing design constraints.
