CD74ACT623M96

Overview

The CD74ACT623M96 is an octal bus transceiver manufactured by Texas Instruments. It features non-inverting logic with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 20-lead small-outline integrated circuit (SOIC) package, specifically the M96 variant. It supports high-level output currents of -24 mA and low-level output currents of 24 mA. The component functions as a registered transceiver with a propagation delay of 12.5 ns. It is designed for surface-mount installation and operates reliably across a temperature range from -55°C to +125°C.

Feature Summary

• Octal bus transceiver architecture providing eight bidirectional data paths
• Three-state outputs enable direct connection to system buses without external drivers
• Registered design allows data storage at the receiver side for timing control
• Non-inverting signal path maintains logical polarity between input and output

Applications

• High-speed data acquisition systems requiring buffered memory interfaces
• Complex digital systems utilizing multiple bus architectures
• Communication modules needing isolated data transfer channels
• Industrial control units operating in wide temperature environments

Procurement Notes

Verify the specific M96 suffix indicates the tape-and-reel packaging format when ordering. Confirm that the ACT logic family requirements match the target system's voltage levels. Ensure the SOIC-20 footprint aligns with the printed circuit board layout specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when an octal width is required for parallel data handling. The ACT series offers faster switching speeds compared to standard AC or HC families. The registered feature distinguishes it from simple transceivers like the 646 series. Consider the thermal dissipation capabilities of the SOIC package for high-density designs.

Part Context

This part belongs to the Texas Instruments CD74ACT family of advanced CMOS logic devices. It serves as a registered version of the unbuffered CD74ACT646. The M96 designation specifies the reel packaging configuration for automated assembly. It complements other bus interface components in complex microprocessor-based systems.

Replacement Considerations

The CD74ACT646M96 is a compatible alternative if registered functionality is not required. Verify pin compatibility and electrical characteristics before substituting. Ensure the replacement part meets the same voltage and current drive specifications.
