SN74LVC1G74RSE2

Flip Flops Overview

The SN74LVC1G74RSE2 is a single positive-edge-triggered D-type flip-flop manufactured by Texas Instruments. It features independent clear and preset inputs, allowing for direct control of the output state. The device operates within a supply voltage range of 1.65V to 3.6V, ensuring compatibility with low-voltage digital systems. Packaged in an ultra-small RSE2 (X2SON) form factor measuring 0.6mm x 0.6mm, it supports surface-mount assembly. Key electrical parameters include a maximum propagation delay of 2.8ns at 3.3V and output drive capabilities of ±24mA, suitable for high-speed logic applications requiring minimal board space.

Flip Flops Feature Summary

• Single positive-edge-triggered D-type flip-flop architecture
• Independent active-low clear and active-high preset inputs
• Ultra-small X2SON package footprint for dense layouts
• Full 5V tolerance on inputs for level shifting

Flip Flops Applications

• Portable consumer electronics with strict space constraints
• Data storage and transfer registers in embedded systems
• Shift registers for serial-to-parallel conversion
• Timing delay elements in clock signal processing

Flip Flops Procurement Notes

Verify the specific suffix 'RSE2' corresponds to the X2SON-5 package configuration during procurement. Confirm that the ordering part number matches the required tape and reel quantity specifications provided in the manufacturer's official documentation. Ensure compliance with RoHS standards and check for automotive qualification if the application requires AEC-Q100 certification, as standard commercial grades may differ from qualified variants.

Flip Flops Selection Notes

Select this component when a single D-flip-flop with dedicated set and reset functions is required in a minimal footprint. The LVC series offers a balance of speed and power consumption suitable for battery-operated devices. Consider the input voltage levels relative to the system logic family; while compatible with 5V systems, operation below 3.6V optimizes power efficiency. Evaluate thermal performance requirements against the small package size for high-density PCB designs.

Flip Flops Part Context

This device belongs to the SN74LVC1Gxx series of single-gate logic ICs designed for low-voltage CMOS operations. The LVC family provides fast switching speeds while maintaining low static power dissipation. The specific model integrates a D-type flip-flop with asynchronous control inputs, distinguishing it from basic memory elements by offering immediate state override capabilities via clear and preset lines without clock dependency.

Flip Flops FAQ

What are the logic states for the clear and preset inputs?

The clear input is active-low, meaning a low signal forces the Q output to a low state. The preset input is active-high, forcing the Q output to a high state when asserted.

Does the device support 5V tolerant inputs?

Yes, the SN74LVC1G74RSE2 features 5V-tolerant inputs, allowing it to interface directly with 5V logic systems even when powered by lower voltages such as 3.3V or 1.8V.
