SN74LS174DB

Flip Flops Overview

The SN74LS174DB is a hex D-type flip-flop manufactured by Texas Instruments in the LS logic series. It features six independent positive-edge-triggered D flip-flops with a common master clear input, housed in a 16-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum propagation delay of 25 ns at 5 V. It functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops triggered on the positive edge of the clock signal
• Includes a common master clear input for synchronous reset functionality
• Provides non-inverting outputs for direct data state observation

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital storage registers
• Shift register configurations for data transmission

Flip Flops Procurement Notes

Verify that the specific SN74LS174DB part number matches the required LS logic family specifications and SOIC-16 package dimensions. Confirm compliance with RoHS directives and ensure the supplier provides valid datasheets from Texas Instruments or authorized distributors to guarantee authenticity and operational reliability.

Flip Flops Selection Notes

Select this component when designing systems requiring multiple independent D-type storage elements within a single integrated circuit. The LS series offers a balance of speed and power consumption suitable for standard 5V logic applications. Ensure the design accommodates the specified voltage limits and thermal requirements for the commercial temperature grade.

Flip Flops Part Context

This component belongs to the widely adopted 74xx logic family, specifically the Low-power Schottky (LS) variant known for improved performance over standard TTL. As a hex flip-flop, it serves as a fundamental building block for sequential logic designs, enabling complex state management and data handling within microcontroller peripheral interfaces and digital control systems.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74LS174N in PDIP packaging or other manufacturers' equivalents such as the MM74LS174. Verify pin compatibility and electrical characteristics before substitution to maintain system integrity.
