CD74AC273M96

Overview

The CD74AC273M96 is an octal D-type flip-flop from the Texas Instruments AC logic series, housed in a 20-pin SOIC package. It features positive edge triggering and true outputs with a master reset function. The device operates on a supply voltage range of 1.5 V to 5.5 V, typically 5 V. It supports a maximum clock frequency of 100 MHz and exhibits a propagation delay of 13.5 ns at 5 V with 50 pF load capacitance. Output drive capability is ±24 mA, with a static current of 8 µA. Operating temperatures span from -55°C to +125°C.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive edge-triggered operation ensuring data capture occurs specifically on the rising clock transition
• Master reset functionality allowing simultaneous clearing of all flip-flop outputs to a low state
• High output drive strength of ±24 mA enabling direct interfacing with heavy capacitive or resistive loads

Applications

• High-speed memory decoding systems requiring balanced propagation delays
• Data routing applications involving parallel-to-serial conversion
• Signal processing circuits utilizing shift register configurations
• Industrial control systems operating across extended temperature ranges

Procurement Notes

Verify the specific suffix M96 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the AC logic family specifications align with the target system's voltage levels and noise immunity requirements. Ensure the 20-SOIC footprint matches the printed circuit board design constraints. Validate compliance with relevant environmental directives such as RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when an octal storage element with high-speed performance is necessary. The AC series offers superior speed compared to standard TTL equivalents while maintaining CMOS power efficiency. Consider the ±24 mA output current for driving multiple downstream inputs without external buffering. Evaluate the wide supply voltage range if the system requires operation below standard 5 V thresholds.

Part Context

This device belongs to the Texas Instruments 74AC logic family, designed for high-speed digital applications. The AC series utilizes advanced CMOS technology to achieve faster switching speeds than previous generations. The CD74AC273 variant specifically provides octal storage capabilities, distinguishing it from quad or single flip-flop counterparts within the same logical architecture.
