MC74ACT652DW

Overview

The MC74ACT652DW is a high-speed CMOS dual 4-bit bus transceiver manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs for effective bus line driving. The device utilizes the 74ACT logic series, providing propagation delays of approximately 9.5 ns at 5 V. It is housed in a 24-SOIC package with surface mount installation, supporting an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual 4-bit configuration enabling simultaneous bidirectional data transfer across two independent buses
• Three-state output design allowing direct connection to system data lines without additional buffering
• CMOS construction ensuring low power consumption while maintaining high-speed switching performance

Applications

• System memory and I/O mapping applications requiring reliable data routing
• Bus-oriented architectures connecting microprocessors to peripheral devices
• Communication systems utilizing standard data transmission protocols

Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 tube packaging format when sourcing. Confirm that the 74ACT logic family requirements align with your target circuit's voltage levels and drive capabilities. Ensure compatibility with existing board layouts regarding pin assignments and thermal management for surface-mount assembly processes.

Selection Notes

Select this component when a dual-channel, non-inverting bus interface is required for 5V CMOS systems. The ACT series offers superior speed compared to standard LS logic while maintaining compatible pinouts. Consider the 24-pin form factor for space-constrained designs needing multiple independent data paths without signal inversion.

Part Context

This part belongs to the 74ACT logic family, which bridges the performance gap between older TTL standards and modern CMOS technologies. It is categorized under bus transceivers within onsemi's standard product portfolio, designed for general-purpose digital logic applications requiring robust signal integrity and noise immunity in industrial environments.

Replacement Considerations

Check for cross-reference parts such as MC74ACT652DWR2 for reel packaging variants or equivalent transceivers from other manufacturers offering identical pinouts and electrical specifications.
