SN74HC273N

Flip Flops Overview

The SN74HC273N is an octal D-type flip-flop from the Texas Instruments HC logic family, housed in a 20-pin PDIP package. It features eight non-inverting outputs and operates within a supply voltage range of 2 V to 6 V. The device exhibits a propagation delay of 160 ns, with high-level output current of -5.2 mA and low-level output current of 5.2 mA. It supports through-hole mounting and functions reliably across an operating temperature range of -40 °C to +85 °C.

Flip Flops Feature Summary

• Contains eight independent D-type edge-triggered flip-flops for parallel data storage
• Provides direct access to all eight input lines and corresponding outputs
• Features CMOS-compatible inputs and push-pull outputs for robust signal integrity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose digital register applications
• Data buffering and temporary storage in microprocessor systems

Flip Flops Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant. Confirm RoHS compliance status via official documentation. Ensure the ordering part number matches the exact manufacturer designation to avoid confusion with surface-mount or automotive-grade equivalents.

Flip Flops Selection Notes

Select this component when through-hole assembly is required for the SN74HC273 function. Verify that the 160 ns propagation delay meets system timing requirements. Ensure the 2 V to 6 V supply voltage range aligns with the target circuit design constraints.

Flip Flops Part Context

This part belongs to the standard SN74HC273 series of octal D-type flip-flops. It serves as a fundamental building block for sequential logic circuits requiring multi-bit data retention. The PDIP-20 package distinguishes it from surface-mount variants like the NSR or QDWRG4Q1.
