SN74HCT273N

Flip Flops Overview

The SN74HCT273N is an octal D-type flip-flop from the Texas Instruments 74HCT series, housed in a 20-pin PDIP package. It features eight positive-edge triggered D-type flip-flops with a common clock and master reset input. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL-level inputs. It provides non-inverting outputs and is designed for through-hole mounting, suitable for industrial applications operating between -40°C and +85°C.

Flip Flops Feature Summary

• Integrates eight independent positive-edge triggered D-type flip-flops within a single integrated circuit
• Features a common clock and master reset input for synchronized data storage and clearing operations
• Accepts TTL logic level inputs while providing CMOS-compatible outputs

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital storage registers
• Industrial control systems requiring robust logic interfacing

Flip Flops Procurement Notes

Verify the specific manufacturer prefix (SN) and suffix (N) to confirm the PDIP package type and commercial temperature rating. Ensure compatibility with existing PCB footprints for 20-pin dual in-line packages. Confirm that the TTL input levels align with the system's logic standards before integration.

Flip Flops Selection Notes

Select this component when a high-density octal register with TTL-compatible inputs is required in a through-hole format. It is appropriate for designs needing a common clock and reset mechanism for multiple data lines. Consider alternative packages like SOIC or TSSOP if surface-mount technology is preferred for the assembly process.

Flip Flops Part Context

This part belongs to the widely used 74HCT logic family, which bridges the gap between older TTL standards and modern CMOS technologies. The HCT series is characterized by its ability to interface directly with TTL devices while offering the lower power consumption typical of CMOS circuits. This specific model represents a standard octal configuration within that lineage.

Flip Flops Replacement Considerations

Equivalent parts include the SN74HC273N for CMOS input compatibility and the SN74HCT273NSR for surface-mount requirements. Cross-reference with NXP 74HCT273 variants for pin-compatible alternatives from other manufacturers.
