MC74HCT574ADTR2G

Flip Flops Overview

The MC74HCT574ADTR2G is an octal D-type flip-flop with three-state outputs manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum propagation delay of 30 ns at 5 V with 50 pF load. The device provides single-ended inputs and outputs, delivering high-level output current of -6 mA and low-level output current of 6 mA. Packaged in a 20-TSSOP surface-mount format, it supports clock frequencies up to 30 MHz and functions across a temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Octal D-type configuration with non-inverting data path
• Three-state output capability for bus driving applications
• CMOS technology compatible with TTL logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in microprocessor systems
• Buffering and latching digital signals

Flip Flops Procurement Notes

Verify the specific suffix ADTR2G confirms the TSSOP-20 package and tape-and-reel shipping method. Confirm RoHS compliance status matches project requirements. Check moisture sensitivity level handling instructions prior to soldering. Ensure the manufacturer part number aligns exactly with design specifications to avoid pinout or electrical characteristic mismatches during integration.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required for 5V CMOS systems. It offers higher speed than standard 74HC series devices due to HCT input compatibility. Consider the 20-TSSOP package for space-constrained PCB layouts. Verify that the 30 ns propagation delay meets system timing constraints for the intended clock frequency.

Flip Flops Part Context

This part belongs to the 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. It serves as a direct replacement for similar octal D-type flip-flops in industrial and consumer electronics. The device integrates eight independent D-type flip-flops with positive-edge triggering into a single integrated circuit solution.

Flip Flops Replacement Considerations

MC74HC574ADTR2G: Similar function but HC series has different input thresholds and wider voltage range. MM74HCT574MTC: Same logical function but packaged in TSSOP tube instead of tape and reel.
