SN74LS175N

Flip Flops Overview

The SN74LS175N is a quad D-type flip-flop integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features a maximum propagation delay of 25.0 ns at 5V with a 15pF load. The device supports a clock frequency up to 40 MHz and provides both inverting and non-inverting outputs. It utilizes a 16-pin DIP package for through-hole mounting and functions reliably across an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Contains four independent positive-edge-triggered D-type flip-flops
• Provides simultaneous complementary Q and Q-bar outputs for each stage
• Includes a common master reset input for synchronous clearing of all stages

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register construction
• Digital timing and sequencing logic

Flip Flops Procurement Notes

Verify the specific manufacturer origin, as Texas Instruments acquired Fairchild Semiconductor's logic portfolio. Confirm that the component matches the original TI specifications rather than legacy Fairchild variants. Ensure the package type corresponds to the required PCB footprint and verify compliance with current environmental standards before finalizing procurement.

Flip Flops Selection Notes

Select this component when a TTL-compatible quad D-flip-flop with complementary outputs is required. It is suitable for designs needing a global reset function and moderate switching speeds. Consider alternative packages like the SOIC variant if surface-mount technology is preferred over through-hole installation.

Flip Flops Part Context

This part belongs to the standard 74LS series of logic devices, widely used in digital electronics for its balance of speed and power consumption. The SN74LS175N serves as a fundamental building block for sequential logic systems, providing reliable data storage capabilities in microprocessor interfaces and control systems.

Flip Flops FAQ

Does the SN74LS175N have individual resets for each flip-flop?

No, it features a single common master reset input that clears all four flip-flops simultaneously.

What is the trigger mechanism for the data inputs?

The flip-flops are triggered on the positive-going edge of the clock signal.
