MC74LVX74DT

Flip Flops Overview

The MC74LVX74DT is a dual D-type flip-flop integrated circuit manufactured by onsemi, belonging to the 74LVX logic series. It operates within a supply voltage range of 2V to 3.6V and features positive edge triggering with complementary outputs. The device contains two independent elements, each handling one bit of data. It is housed in a 14-TSSOP package with a width of 4.40mm. Key electrical specifications include a maximum propagation delay of 13.2ns at 3.3V with 50pF load, a clock frequency of 85 MHz, and quiescent current of 2 µA. Output drive capability is specified at 4mA for both high and low states.

Flip Flops Feature Summary

• Dual D-type flip-flop architecture with positive edge triggering
• Complementary output configuration for versatile signal interfacing
• Low-voltage CMOS technology supporting 2V to 3.6V operation
• Surface-mount TSSOP-14 packaging for compact board integration

Flip Flops Applications

• Data storage and register applications in low-voltage digital systems
• State machine implementation in portable electronic devices
• Synchronization circuits for asynchronous signal processing
• Memory interface buffering in consumer electronics

Flip Flops Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm package marking matches the 14-TSSOP specification and check for RoHS compliance documentation. Ensure the part number suffix corresponds to the specific tape-and-reel or tube packaging variant required for your assembly process. Review recent obsolescence notices as this family may have lifecycle changes.

Flip Flops Selection Notes

Select this component when dual independent D-type storage is required in space-constrained designs. The LVX series offers compatibility with 3.3V and 2.5V logic levels, making it suitable for mixed-voltage environments. Consider the 13.2ns propagation delay for timing-critical paths. Verify that the 4mA output current meets the driving requirements of downstream loads without additional buffering.

Flip Flops Part Context

This device is part of the broader 74LVX family, which provides low-voltage CMOS performance with speed comparable to 5V TTL equivalents. The MC74LVX74DT specifically addresses the need for dual flip-flops in portable and battery-operated applications where power efficiency and small form factor are critical design constraints.

Flip Flops Replacement Considerations

MC74LVX74DTG is a verified lead-free variant from onsemi. Cross-manufacturer substitutes such as NXP versions exist but require pinout and electrical parameter verification.
