CD74HCT174MT

Overview

The CD74HCT174MT is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments. It functions as a D-type flip-flop with positive-edge triggering, containing one element of six bits. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 25 MHz. It features a maximum propagation delay of 40 ns at 4.5 V with 50 pF load capacitance. The component utilizes a 16-SOIC package with dimensions of 0.154 inches (3.90 mm) width. It includes a master reset function and non-inverting outputs. The static current consumption is 8 µA, with output drive currents of 4 mA for both high and low states. The input capacitance is specified at 10 pF.

Feature Summary

• Positive-edge triggered D-type flip-flop architecture providing reliable data capture on clock transitions.
• Integrated master reset functionality for synchronous initialization of the six-bit register state.
• High-speed CMOS technology enabling operation up to 25 MHz clock frequencies with low power consumption.
• Non-inverting output configuration suitable for direct interfacing with subsequent logic stages.

Applications

• Parallel data storage in digital systems requiring six-bit word retention.
• Shift register construction through cascading multiple units for serial-to-parallel conversion.
• Timing control circuits utilizing the positive-edge trigger characteristic for synchronization.

Procurement Notes

Verify the specific suffix MT indicates tape and reel or cut tape packaging options when sourcing. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Check for end-of-life notices, as production status may have changed. Ensure the 16-SOIC package footprint matches the target PCB design constraints. Validate operating temperature range requirements against the -55°C to 125°C specification.

Selection Notes

Select this component for applications requiring a single six-bit D-type flip-flop in surface-mount form factor. Consider the 40 ns propagation delay for timing budget analysis in high-speed designs. Evaluate the 4 mA output drive capability against load requirements. Compare against other 74HCT series devices if different bit widths or inversion types are needed. Ensure supply voltage stability within the 4.5 V to 5.5 V window for optimal performance.
