CD74HC273M96

Overview

The CD74HC273M96 is a high-speed CMOS logic octal D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with positive-edge triggering and an asynchronous active-low reset input. The device operates within a supply voltage range of 2 V to 6 V, supporting propagation delays of up to 150 ns. It provides non-inverting outputs with drive capabilities of ±5.2 mA. Packaged in a 20-pin SOIC (SOIC-20) surface-mount format, it functions reliably across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Contains eight independent positive-edge triggered D-type flip-flops for parallel data storage
• Includes an asynchronous active-low master reset input to clear all outputs simultaneously
• Supports wide supply voltage operation ranging from 2 V to 6 V for flexible system integration

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component matches the required HC logic family characteristics and SOIC-20 footprint dimensions before integration. Cross-reference the datasheet revision date to validate electrical parameters and operating conditions.

Selection Notes

Select this component when an octal D-type flip-flop with a dedicated reset function is required. The HC series offers standard CMOS performance suitable for general-purpose logic applications. Consider the 2 V to 6 V supply range and 150 ns propagation delay for timing analysis. Verify that the SOIC-20 package aligns with the target PCB layout constraints.

Part Context

This part belongs to the CD74HC273 series of octal D-type flip-flops. It is distinct from the CD74HCT273, which utilizes TTL-compatible input thresholds. Unlike the CD74HC574, this variant lacks tri-state outputs, providing standard single-ended outputs instead. The 'M96' suffix typically denotes the specific reel packaging configuration for surface-mount assembly.
