SN74LVC1G74DQER

Flip Flops Overview

The SN74LVC1G74DQER is a single positive-edge-triggered D-type flip-flop from Texas Instruments, featuring independent clear and preset inputs. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes an X2SON-8 package. The device supports TTL and CMOS input logic levels, ensuring compatibility with various digital systems. Key electrical characteristics include a maximum propagation delay of 5 ns at 3.3 V with a 50 pF load, and output drive capabilities of ±32 mA. It functions reliably across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides single-channel D-type flip-flop functionality with dedicated asynchronous clear and preset controls for precise state management.
• Supports low-voltage operation down to 1.65 V, enabling energy-efficient performance in portable and battery-powered applications.
• Features Schmitt-trigger inputs on the clock line to ensure clean signal transitions and noise immunity.

Flip Flops Applications

• Data storage and register circuits in embedded systems
• Shift registers for serial-to-parallel data conversion
• Timing and synchronization logic in communication interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'DQER' corresponds to the X2SON-8 package and tape-and-reel configuration required for your assembly process. Confirm that the AEC-Q100 qualification status meets automotive reliability standards if applicable. Ensure the operating voltage range aligns with your system's power rails before finalizing procurement.

Flip Flops Selection Notes

Select this component when a compact, low-power D-type flip-flop with independent control inputs is required. The X2SON-8 package offers space savings compared to standard SOIC options. Consider the 1.65 V minimum supply voltage for compatibility with modern low-voltage logic families. Verify that the 5 ns propagation delay meets your timing constraints.

Flip Flops Part Context

This part belongs to the SN74LVC1Gxx series of single-gate logic devices designed for ultra-low voltage applications. The LVC family provides high-speed performance while maintaining low power consumption. The SN74LVC1G74 variant specifically implements D-type flip-flop logic with set and reset capabilities, serving as a fundamental building block for sequential logic circuits in consumer and industrial electronics.

Flip Flops Replacement Considerations

SN74LVC1G74DCKR: Similar LVC series flip-flop in SC-70-5 package; verify pinout compatibility. SN74AUP1G74DQER: Higher speed AUP series alternative in X2SON-8; requires 2.3 V minimum supply voltage check.
