SN74HC273NE4

Flip Flops Overview

The SN74HC273NE4 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic series. It features eight independent positive-edge triggered D-type flip-flops with a common clock (CP) and master reset (MR) input. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole installation in a PDIP-20 package. Key electrical parameters include a propagation delay of 160 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It functions as a non-inverting CMOS logic device with a standard operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight positive-edge triggered D-type flip-flops with independent data inputs and true outputs.
• Features a common clock input for synchronized data latching across all flip-flops.
• Includes a master reset input that forces all outputs low independently of clock or data states.

Flip Flops Applications

• Digital register designs requiring parallel data storage
• State machine implementations in control systems
• Counter circuits utilizing shared clock synchronization

Flip Flops Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to the intended RoHS-compliant version and packaging configuration. Confirm that the PDIP-20 through-hole package aligns with the target PCB footprint requirements. Ensure the component meets the required industrial temperature specifications for the intended application environment before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with a common clock and master reset is required in a through-hole design. The HC series offers compatibility with standard CMOS logic levels and provides sufficient drive current for general digital applications. Consider the PDIP-20 package constraints and verify that the 160 ns propagation delay meets the timing requirements of the system clock speed.

Flip Flops Part Context

This part belongs to the SN74HC273 family of octal D-type flip-flops produced by Texas Instruments. The 'NE4' suffix indicates a specific manufacturing variant, typically denoting lead-free construction and compliance with environmental standards. It serves as a fundamental building block for sequential logic circuits, providing reliable data storage capabilities within the broader 74HC logic ecosystem.
