SN74HC374AN

Flip Flops Overview

The SN74HC374AN is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 70 MHz. The device utilizes a 20-pin PDIP package with through-hole mounting. Key electrical specifications include a propagation delay of 14 ns, high-level output current of -7.8 mA, and low-level output current of 7.8 mA. It functions reliably across an operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Octal configuration providing eight independent positive-edge-triggered D-type flip-flops for parallel data storage.
• Three-state outputs allow direct connection to bus systems without additional interface components.
• High-current drive capability enables operation with high capacitive or low-impedance loads.
• Low static power consumption ensures efficient performance in battery-powered applications.

Flip Flops Applications

• Buffer registers for temporary data storage in digital circuits
• I/O port expansion for microcontroller interfaces

• Working registers in computing architectures

Flip Flops Procurement Notes

Verify the specific suffix 'AN' corresponds to the 20-pin PDIP package when ordering. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected distributor provides traceable manufacturing data. Check for any recent Product Change Notifications regarding pinout or material composition updates before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component for designs requiring wide voltage flexibility between 2 V and 6 V. The HC series offers CMOS input compatibility with TTL output drive strength. Consider the PDIP package for prototyping or through-hole assembly requirements. Evaluate the 70 MHz clock limit against system timing constraints to ensure reliable data capture at desired frequencies.

Flip Flops Part Context
