SN74F174AN

Flip Flops Overview

The SN74F174AN is a hex D-type flip-flop from the Texas Instruments F/FAST logic series. It features six independent positive-edge-triggered circuits with non-inverting outputs in a 16-pin PDIP package. The device operates on a 4.5 V to 5.5 V supply, supporting TTL input and output levels. Key electrical parameters include a propagation delay of 10 ns, a low-level output current of 20 mA, and a high-level output current of -1 mA. It functions within a commercial temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops triggered by the positive edge of the clock signal.
• Provides true (non-inverting) outputs for direct logic interfacing.

Flip Flops Applications

• High-speed digital data storage and register applications
• Parallel-to-serial conversion circuits
• State machine implementation

Flip Flops Procurement Notes

Verify component authenticity through authorized channels or original manufacturer documentation. Confirm that the physical package matches the specified PDIP-16 configuration and that the marking aligns with the SN74F174AN designation. Ensure compliance with relevant environmental standards as indicated in official datasheets before integration into final products.

Flip Flops Selection Notes

Select this component when a fast, six-channel D-type flip-flop with standard TTL compatibility is required. The F-series offers higher speed than HC variants but consumes more power. Verify that the system voltage remains within the 4.5 V to 5.5 V range and that the through-hole mounting style fits the PCB layout requirements.

Flip Flops Part Context

This part belongs to the SN74F family, designed for high-speed operations using Schottky diodes to prevent saturation. It serves as a core memory element in digital systems, distinct from octal variants like the SN74F374N which contain eight flip-flops. The 'A' suffix typically denotes specific manufacturing revisions or pinout consistency within the series.

Flip Flops Replacement Considerations

SN74LS174AN: Offers slower switching speeds but lower power consumption; suitable for general-purpose timing where speed is not critical. SN74ALS174AN: Provides comparable speed to the F-series with significantly reduced power dissipation, serving as a direct low-power replacement.
