SN74LS173ADRG4

Flip Flops Overview

The SN74LS173ADRG4 is a 4-bit D-type register from the Texas Instruments LS logic series, housed in a 16-pin SOIC surface-mount package. It features 3-state outputs and operates on a single supply voltage ranging from 4.75 V to 5.25 V. The device supports positive-edge triggering and functions within an operating temperature range of 0°C to +70°C. Designed for TTL input compatibility, it provides non-inverting logic functionality with a propagation delay of approximately 30 ns.

Flip Flops Feature Summary

• Contains four independent D-type flip-flops with 3-state output capability
• Positive-edge triggered clocking mechanism for data synchronization
• Compatible with standard TTL input voltage levels
• Non-inverting logic polarity for direct signal transmission

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Temporary storage registers in digital systems
• Shift register configurations for data processing
• Interface buffering between logic families

Flip Flops Procurement Notes

Verify the specific suffix 'ADRG4' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Ensure the component matches the required SOIC-16 footprint and pinout specifications for your PCB design. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a compact surface-mount solution is required for 4-bit data storage with bus isolation capabilities. The LS series offers a balance of speed and power consumption suitable for general-purpose digital applications. Consider the 3-state feature if multiple devices share a common data bus. Verify that the 5V supply voltage aligns with the system's power architecture.

Flip Flops Part Context

This part belongs to the SN74LS173A family of 4-bit D-type registers. The 'A' variant typically denotes improved switching characteristics over earlier versions. The 'R' suffix indicates reel packaging, while 'G4' signifies lead-free construction compliant with environmental directives. This family is widely used in legacy and modern mixed-signal designs requiring reliable data latching.

Flip Flops Replacement Considerations

Direct replacements include SN74LS173AN (PDIP) or SN74LS173NSR (SOIC). Verify pin compatibility and electrical parameters before substitution. Alternative logic families like HC or ALS may require voltage level adjustments.
