SN74LS171D

Flip Flops Overview

The SN74LS171D is a quadruple D-type flip-flop manufactured by Texas Instruments in the LS logic series. It features positive edge triggering and an asynchronous clear function. The device operates within a supply voltage range of 4.75 V to 5.25 V. It utilizes a 16-pin SOIC surface-mount package with dimensions of 10 mm length, 4 mm width, and 1.5 mm height. The component supports a maximum operating temperature of +70 °C and a minimum of 0 °C.

Flip Flops Feature Summary

• Contains four independent D-type flip-flops sharing a common clock signal
• Includes an asynchronous clear input for immediate state reset
• Utilizes positive edge-triggered data capture mechanism

Flip Flops Applications

• Data storage registers in digital systems
• Shift register configurations
• Frequency division circuits

Flip Flops Procurement Notes

Verify that the specific SN74LS171D variant matches the required LS logic family specifications. Confirm the SOIC-16 package type aligns with PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the target application. Check RoHS compliance status as indicated in official documentation.

Flip Flops Selection Notes

Select this component when quadruple D-type storage with asynchronous clearing is required. The LS series offers standard propagation delays suitable for general-purpose logic applications. The SOIC package facilitates automated surface-mount assembly processes. Consider the 5V supply requirement and limited temperature range during system design.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74xxLS series of bipolar logic devices. It provides quadruple D-type flip-flop functionality within a single integrated circuit. The device is designed for standard 5V logic systems requiring reliable data storage and transfer capabilities.

Flip Flops Replacement Considerations

Compatible substitutes include other quadruple D-type flip-flops from the 74LS series such as the SN74LS173 or SN74LS174, provided pin compatibility and functional requirements are verified.
