MC74ACT652DWR2

Overview

The MC74ACT652DWR2 is an obsolete 8-bit bus transceiver from onsemi's 74ACT logic family. It features non-inverting data transmission with three-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. Packaged in a 24-pin SOIC (Wide) format, it provides robust drive capabilities suitable for memory and microcontroller interfacing.

Feature Summary

Provides bidirectional 8-bit data transfer between two buses
Features non-inverting logic function for direct signal routing
Includes three-state outputs to isolate the bus during inactive states
Supports TTL-compatible input voltage levels for system integration

Applications

Memory mapping systems requiring address/data bus isolation
Microcontroller-to-peripheral interface circuits
Bidirectional bus drivers in embedded control systems

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement parts. Do not assume functional equivalence with similar part numbers without consulting official substitution guides. Confirm package dimensions and pinout compatibility before integrating any alternative components into existing designs.

Selection Notes

Engineers should prioritize the recommended substitute MC74ACT652DWR2G due to the original model's discontinued status. Ensure that the selected replacement maintains identical pin configurations and electrical characteristics to avoid redesigning the printed circuit board. Verify that the new component meets the specific voltage and speed requirements of the target application.

Part Context

The MC74ACT652DWR2 belongs to the 74ACT series, which combines CMOS low power consumption with TTL-compatible speeds. This specific model functions as an octal bus transceiver, facilitating efficient data movement in complex digital architectures. Its wide SOIC package allows for standard surface-mount assembly techniques commonly used in industrial electronics manufacturing.
