CD74HCT74MTE4

Overview

The CD74HCT74MTE4 is a high-speed CMOS dual D-type flip-flop manufactured by Texas Instruments. It features positive-edge triggering and independent clear and preset inputs for each flip-flop within a single package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 25 MHz. It utilizes a 14-pin SOIC surface-mount package with an operating temperature range from -55°C to +125°C. Propagation delay is specified at 30 ns, with output drive capabilities of 8 mA low-level and -8 mA high-level current.

Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• Independent asynchronous clear and preset control inputs
• High-speed CMOS technology compatible with TTL logic levels

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to the prevalence of counterfeit integrated circuits in the market. Confirm that the specific suffix 'E4' matches the required lead-free and RoHS-compliant specifications for your assembly process. Ensure the SOIC-14 footprint aligns with your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when dual edge-triggered storage is required in a compact surface-mount format. The HCT series ensures compatibility with standard 5V TTL logic families. Consider the 125°C maximum operating temperature for industrial applications. Verify that the 25 MHz speed rating meets the timing requirements of the target system design.

Part Context

This part belongs to the Texas Instruments CD74HCTxx family of high-speed CMOS logic devices. It shares pinout and functional characteristics with other members of the 74HCT series, such as the CD74HCT74M. The 'M' designation indicates the SOIC package type, while 'E4' specifies environmental compliance attributes including lead-free construction.
