MC74HC174ADR2

Flip Flops Overview

The MC74HC174ADR2G is a Hex D-Type Flip-Flop from the onsemi 74HC series, housed in a 16-SOIC package. It features six independent D-type flip-flops with positive-edge triggering and an asynchronous active-low reset input. The device operates within a supply voltage range of 2 V to 6 V, supporting single-ended inputs and outputs. Key electrical parameters include a propagation delay of 110 ns, output current capabilities of ±5.2 mA, and a maximum clock frequency of 35 MHz at 6 V. It functions across an extended temperature range of -55°C to +125°C.

Flip Flops Feature Summary

• Integrates six independent D-type flip-flops with positive-edge clock triggering for parallel data storage.
• Includes an asynchronous active-low reset input to clear all outputs simultaneously regardless of clock state.
• Supports wide supply voltage operation from 2 V to 6 V for flexible system integration.
• Features high noise immunity and low static power consumption typical of CMOS technology.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital memory storage elements
• Timing and control logic systems

Flip Flops Procurement Notes

Verify the specific ordering suffix 'R2' against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the RoHS-compliant variant (typically ending in G) if environmental compliance is required. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates prior to final design approval.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with asynchronous reset is required in a surface-mount SOIC-16 package. Consider the 74HC series for compatibility with standard TTL logic levels while operating at lower voltages than HCT variants. Evaluate the 110 ns propagation delay and 35 MHz clock speed against system timing requirements to ensure adequate performance margins.

Flip Flops Part Context

Flip Flops FAQ

What is the function of the MR (Master Reset) pin?

The MR pin provides an asynchronous active-low reset. When driven low, it forces all six Q outputs to a low state immediately, independent of the clock signal.

How does the positive-edge triggering work in this device?

The flip-flops capture the logic level present at the D inputs only at the rising edge of the CLK signal. Data changes occurring between clock edges do not affect the outputs.
