SN74ALS175D

Flip Flops Overview

The SN74ALS175D is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features positive-edge triggering and includes a master reset input for synchronous data storage applications. The device is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package designed for surface-mount technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a standard operating temperature range from 0°C to +70°C. Key electrical characteristics include a propagation delay of 17 ns, a low-level output current capability of 8 mA, and a high-level output current of -400 µA.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit package.
• Positive-edge triggering mechanism ensures data capture occurs at the rising edge of the clock signal.
• Master reset functionality allows for immediate clearing of all flip-flop outputs simultaneously.

Flip Flops Applications

• Synchronous data storage and register implementation in digital systems
• State machine design requiring multiple sequential logic elements
• Parallel-to-serial data conversion circuits

Flip Flops Procurement Notes

Verify that the specific part number matches the SOIC-16 package variant rather than the PDIP-14 through-hole version. Confirm RoHS compliance status and check for any recent product change notifications regarding pinout or electrical specifications before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal flip-flop solution with fast switching speeds is required. The ALS series offers a balance between power consumption and speed suitable for general-purpose logic applications. Ensure the design accommodates the specified output drive currents and operating temperature constraints.

Flip Flops Part Context

This device is part of the SN74ALS175 family, which includes variants such as the SN74ALS175N (PDIP) and SN74ALS175DR (SOIC). It serves as a core sequential logic element within the broader Texas Instruments 74-series logic portfolio, providing reliable data retention capabilities for complex digital designs.

Flip Flops Replacement Considerations

SN74ALS175DR is a direct equivalent offering the same functional specifications in a tape-and-reel packaging format for automated assembly processes.
