SN74HC174NG4

Flip Flops Overview

The SN74HC174NG4 is a hex D-type flip-flop manufactured by Texas Instruments, belonging to the SN74HC series. It features six independent D-type flip-flops with positive-edge triggering and an asynchronous master reset (clear) input. The device operates within a wide supply voltage range of 2 V to 6 V and utilizes Schmitt-trigger inputs for noise immunity. It is housed in a 16-pin PDIP package and supports surface-mount or through-hole installation depending on the specific variant configuration.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops with positive-edge clocking
• Includes an asynchronous master reset (clear) function for all stages
• Features Schmitt-trigger inputs to improve noise tolerance
• Supports a wide operating supply voltage range from 2 V to 6 V

Flip Flops Applications

• Parallel data storage and buffering in digital systems
• Shift register configurations for serial-to-parallel conversion
• State machine implementation in control logic circuits
• General-purpose timing and sequencing applications

Flip Flops Procurement Notes

Verify the package type matches the design requirements, as the 'N' suffix typically indicates a plastic dual-in-line package (PDIP). Confirm that the ordering suffix 'G4' aligns with current manufacturing specifications and environmental compliance standards such as RoHS. Cross-reference the manufacturer's latest datasheet to ensure pinout compatibility and electrical characteristics match the target application before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when a high-density solution requiring six independent D-type flip-flops is necessary within a single package. The HC series offers standard CMOS performance suitable for general-purpose logic applications. Consider the propagation delay and output drive capabilities relative to the system clock speed. Ensure the chosen package style accommodates the PCB layout constraints and assembly method required for the specific product design.

Flip Flops Part Context

The SN74HC174 is part of Texas Instruments' extensive family of high-speed CMOS logic devices. This series is designed to provide performance comparable to low-power Schottky TTL while offering lower power consumption. The hex configuration allows for significant space savings in circuit designs compared to using multiple individual flip-flop ICs, making it a common choice for complex digital logic implementations.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74HC174N and SN74HC174DR, which share identical logical functionality and pinouts. Verify that alternative packages maintain the same electrical parameters and operating temperature ranges. Ensure that any replacement part meets the same environmental and regulatory standards required for the original design specification.
