SN74LS174NS

Flip Flops Overview

The SN74LS174NS is a hex D-type flip-flop integrated circuit manufactured by Texas Instruments. It belongs to the Low-Power Schottky (LS) logic series and features six independent D-type flip-flops with positive-edge triggering. The device includes a master clear input for synchronous reset functionality. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 30 MHz. The component is housed in a 16-pin SOIC surface-mount package, measuring 10 mm in length, 4 mm in width, and 1.5 mm in height. It is rated for operation between 0°C and +70°C.

Flip Flops Procurement Notes

Verify the specific suffix 'N' against official Texas Instruments documentation to confirm the exact package variant and pinout configuration. Ensure that the procurement source provides valid RoHS compliance certificates matching the current manufacturing standards. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability before finalizing acquisition.

Flip Flops Selection Notes

Select this component when designing circuits requiring multiple independent storage elements within a single package. The LS series offers a balance of speed and power efficiency suitable for standard TTL applications. Consider the SOIC package dimensions for PCB layout constraints. Verify that the system operating temperature range falls within the specified commercial limits to ensure reliable performance.

Flip Flops Part Context

This device is part of the extensive 74xx logic family, widely used in digital electronics for basic state retention. The SN74LS174NS specifically addresses designs needing six bits of storage without external wiring complexity. It serves as a fundamental building block for counters, registers, and memory interfaces in industrial and consumer electronic applications.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74LS174AD and SN74LS174DR. These variants maintain identical logical functionality but differ in packaging type or reel specifications. Verify pin compatibility and electrical characteristics before substitution.
