SN74AHCT174N

Flip Flops Overview

The SN74AHCT174N is a hex D-type flip-flop manufactured by Texas Instruments, featuring positive-edge triggering and a master reset function. It operates within a supply voltage range of 4.5V to 5.5V, delivering high-speed performance with a maximum propagation delay of 8.8ns at 5V with 50pF load. The device supports clock frequencies up to 115 MHz and provides non-inverting outputs with 8mA drive capability for both high and low states. Designed for through-hole mounting in a 16-PDIP package, it ensures reliable operation across an industrial temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Positive-edge triggered D-type flip-flops with master reset functionality
• High-speed logic performance supporting clock frequencies up to 115 MHz
• Robust output drive capability with 8mA source and sink currents
• Compatible with CMOS and TTL inputs via AHCT logic series

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations for data storage and transfer
• Timing and synchronization elements in digital systems
• State machine implementation in control logic

Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package type, as variations exist for tape-and-reel or tube packaging. Confirm that the application environment remains within the specified -40°C to 85°C operating temperature range. Ensure power supply stability between 4.5V and 5.5V to maintain signal integrity. Check for RoHS3 compliance requirements if environmental regulations apply to the final assembly.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with positive-edge triggering and a global reset is required. The AHCT series ensures compatibility with both 5V CMOS and 3.3V TTL logic levels. Consider the 16-PDIP package only if through-hole mounting is necessary for mechanical stability or prototyping. Evaluate the 8.8ns propagation delay against system timing constraints to ensure adequate setup and hold times are met.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AHCT1xx series, which combines advanced CMOS technology with TTL-compatible input structures. The 'HCT' designation indicates high-speed CMOS with TTL-compatible voltages, while '174' identifies the specific hex D-flip-flop topology. This family is designed for general-purpose digital applications requiring reliable state storage and high-speed data processing capabilities.

Flip Flops Replacement Considerations

Direct functional equivalents include other hex D-type flip-flops from the same logic family, such as the SN74AHCT174DR (SOIC package) or SN74AHCT174PW (TSSOP package). Cross-family replacements like the SN74HC174 offer similar functionality but may require voltage level adjustments due to different input threshold characteristics.
