CD74AC574M96

Overview

The CD74AC574M96 is an octal D-type flip-flop with three-state outputs from the Texas Instruments AC logic series. It features a 20-pin SOIC surface-mount package and operates on a single supply voltage ranging from 1.5 V to 5.5 V. The device provides non-inverting data paths with balanced propagation delays of 135 ns at 5 V. It supports high drive currents of ±24 mA and functions reliably across an extended industrial temperature range of -55 °C to +125 °C.

Feature Summary

• Octal configuration providing eight independent D-type storage elements within a single integrated circuit
• Three-state output capability allowing direct connection to bus systems without additional buffering hardware
• CMOS construction ensuring low static power consumption while maintaining high noise immunity margins

Applications

• High-speed memory decoding circuits requiring precise timing control
• Data routing applications in telecommunications equipment
• Signal conversion interfaces between different logic families
• Parallel-to-serial data transfer modules in embedded systems

Procurement Notes

Verify that the specific M96 suffix corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure that the ordering quantity aligns with standard reel sizes to avoid partial reel handling issues during production.

Selection Notes

Select this component when designing systems requiring multiple synchronized storage elements with minimal board space. The AC series offers superior speed compared to standard HC variants while maintaining CMOS compatibility. Consider the three-state outputs for efficient bus architecture implementation where multiple devices share common data lines.

Part Context

This part belongs to the extensive CD74AC family of complementary metal-oxide-semiconductor logic devices. The AC series represents a performance tier positioned between older LS and newer AHC technologies. It maintains pinout compatibility with legacy designs while offering improved switching speeds and lower power dissipation characteristics suitable for modern digital applications.

Replacement Considerations

CD74AC574N serves as a direct through-hole alternative with identical electrical specifications. CD74ACT574 provides compatible functionality with TTL-compatible input thresholds for mixed-voltage system integration.
