74LVX74TTR

Overview

The 74LVX74TTR is a dual D-type flip-flop manufactured by STMicroelectronics, belonging to the LVX logic series. It features positive-edge triggering with set and reset inputs. The device operates within a supply voltage range of 2 V to 3.6 V and utilizes CMOS technology. It is housed in a TSSOP-14 surface-mount package. Key electrical parameters include a maximum propagation delay of 9 ns at 3.3 V with 50 pF load, and output currents of 4 mA for both high and low states. The component supports an operating temperature range from -55°C to +125°C.

Feature Summary

• High noise immunity with Schmitt trigger characteristics on inputs

Applications

• Data storage and register applications
• Shift registers and serial-to-parallel conversion
• Timing and synchronization circuits
• State machines and control logic

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot codes against current datasheets. Check for obsolescence notices as availability may be limited. Ensure proper handling procedures are followed due to sensitivity to electrostatic discharge during installation.

Selection Notes

Select this component for designs requiring dual D-flip-flops in low-voltage environments. Verify that the 2 V to 3.6 V supply range matches system requirements. Consider the TSSOP-14 package constraints for PCB layout. Evaluate propagation delay specifications against timing constraints. Ensure input voltage levels are compatible with driving signals.

Part Context

This part belongs to the 74LVX family of low-voltage CMOS logic devices. It provides pin-compatible functionality with standard 74-series logic but optimized for lower voltage operation. The TTR suffix indicates tape and reel packaging suitable for automated assembly processes. It is designed for high-speed digital applications requiring low power dissipation.

Replacement Considerations

Direct substitutes include SN74LVX74ADBR from Texas Instruments and MC74LVX74DR2G from onsemi. These alternatives offer similar pinouts and logical functions. Verify voltage ranges and package dimensions before substitution. Cross-reference datasheets for any differences in switching characteristics or thermal performance.
