TC74HC574AP

Flip Flops Overview

The TC74HC574AP is an octal D-type flip-flop with 3-state outputs from the HC/UH series, manufactured by Toshiba Semiconductor and Storage. It utilizes silicon gate CMOS technology for high-speed operation comparable to LSTTL while maintaining low power dissipation. The device features non-inverting outputs controlled by a clock input (CK) and an output enable input (OE). It operates within a supply voltage range of 2V to 6V and supports a maximum operating frequency of 24 MHz at nominal supply. The package is a 20-pin PDIP.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive edge-triggered data storage
• Three-state output capability allowing bus line driving applications
• CMOS inputs compatible with standard CMOS and LSTTL outputs via pull-up resistors
• Built-in protection circuits against static discharge and transient excess voltage

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Bus-oriented memory register implementations
• I/O port expansion in microprocessor systems
• General-purpose storage elements in digital logic designs

Flip Flops Procurement Notes

Verify the specific suffix 'AP' corresponds to the PDIP-20 package variant in official Toshiba documentation. Confirm RoHS compliance status as historical data indicates variations between leaded and lead-free versions for this series. Ensure the supplier provides valid datasheets matching the TC74HC574A family specifications before ordering.

Flip Flops Selection Notes

Select this component when an octal latch with tri-state outputs is required for bus interfacing. It offers high noise immunity and low static power consumption typical of HC CMOS. Consider the PDIP-20 package for through-hole prototyping or legacy board designs requiring this specific form factor.

Flip Flops Part Context

This part belongs to the TC74HC574A family of octal D-type flip-flops. It shares functional equivalence with industry-standard 74HC574 devices but is fabricated using Toshiba's specific silicon gate CMOS process. The 'A' suffix denotes improved speed and electrical characteristics compared to earlier generations.

Flip Flops Replacement Considerations

Direct substitutes include MC74HC574AFEL and SN74HC574DWR. Verify pinout compatibility and electrical parameters such as propagation delay and output drive current when cross-referencing with other manufacturers' equivalents.
