SN74AC74NE4

Flip Flops Overview

The SN74AC74NE4 is a dual D-type flip-flop from the Texas Instruments AC logic series, housed in a 14-pin PDIP package. It operates on a supply voltage range of 2 V to 6 V with a maximum propagation delay of 14 ns. The device features CMOS inputs and outputs, providing high-level output currents of -24 mA and low-level output currents of 24 mA. Designed for through-hole mounting, it supports an operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Dual positive-edge-triggered D-type flip-flops with set and reset functionality
• CMOS input and output structures for compatibility
• High noise immunity and wide operating voltage range

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage elements

Flip Flops Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and environmental compliance. Ensure the component matches the required PDIP-14 through-hole configuration. Cross-reference the datasheet revision date to validate technical specifications before integration into designs.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with AC logic speed and through-hole packaging is required. It is suitable for applications needing 2 V to 6 V operation and standard CMOS interface levels. Consider alternative packages if surface-mount technology is preferred for the same logical function.

Flip Flops Part Context

This part belongs to the SN74AC74 family of dual D-type flip-flops. It shares logical functionality with variants such as SN74AC74N and SN74AC74PWR but differs in physical packaging. The NE4 suffix typically indicates lead-free construction within the Texas Instruments product line.
