54ACTQ245/B2A

Overview

The 54ACTQ245/B2A is a dual-marked bus transceiver manufactured by Rochester Electronics, LLC. It corresponds to the military-grade part number 5962-9218701M2A. The device is an 8-bit, single-function CMOS bus driver/transceiver with true output polarity. It features three-state outputs and direction control capabilities. The component is designed for high-speed data transmission applications requiring reliable signal integrity in demanding environments.

Feature Summary

• Provides bidirectional data transfer between two buses using eight bits of data width
• Features three-state outputs to prevent bus contention during inactive periods
• Includes direction control functionality to manage data flow orientation

Applications

• Military and aerospace electronic systems
• High-reliability industrial control equipment
• Data communication interfaces requiring strict signal integrity

Procurement Notes

Verify the dual marking (5962-9218701M2A) on the component surface to confirm authenticity. Ensure the supplier provides traceability documentation linking the lot to authorized manufacturing sources. Check for RoHS compliance status as indicated in product specifications. Confirm package integrity upon receipt to avoid handling damage.

Selection Notes

Select this component when a ruggedized, 8-bit bus transceiver is required for mission-critical applications. It serves as a direct replacement for standard commercial variants in harsh environments. Consider its CMOS technology for low power consumption relative to older TTL families. Evaluate pin compatibility with existing PCB layouts before integration.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductors. This part represents a continuation of legacy military-grade components originally produced by major manufacturers. The company ensures supply continuity for critical infrastructure that cannot easily transition to newer generations.

Replacement Considerations

Direct substitute: 5962-9218701M2A. Verify pinout compatibility with original design. Ensure voltage levels match system requirements.
