SN74HCT74NE4

Flip Flops Overview

The SN74HCT74NE4 is a dual D-type positive-edge-triggered flip-flop manufactured by Texas Instruments. It features independent clock, preset, and clear inputs for each flip-flop within a single 14-pin PDIP package. The device operates within a supply voltage range of 2V to 6V and supports data rates up to 37 MHz at 5V. It includes an internal clearing mechanism that activates upon power-up. The component is designed for industrial temperature ranges from -40°C to 85°C.

Flip Flops Procurement Notes

Verify the presence of the 'E4' suffix to confirm lead-free compliance and RoHS status as specified by Texas Instruments. Ensure the ordering part number matches the exact package style and temperature grade required for the target application environment. Cross-reference the manufacturer's official documentation for any recent product lifecycle or availability updates.

Flip Flops Selection Notes

Select this component when dual independent storage elements are required in a through-hole DIP package. The HCT logic family ensures compatibility with TTL-level inputs while operating on CMOS supply voltages. Consider the 37 MHz maximum frequency limit for high-speed timing requirements and verify that the 14-pin footprint fits the PCB layout constraints.
