74FCT162245CTPVCG4

Overview

The Texas Instruments 74FCT162245CTPVCG4 is a 16-bit bidirectional bus transceiver belonging to the FCT logic series. It integrates two independent 8-bit transceivers within a single package, facilitating data transfer between two buses with direction control. The device operates at a supply voltage of 4.5V to 5.5V and features true outputs with three-state capability. It utilizes a 48-pin SSOP surface-mount package and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Provides dual 8-bit bidirectional data paths for efficient system interconnects
• Features balanced output drivers designed to reduce system switching noise
• Includes power-off disable functionality to permit live insertion without bus contention

Applications

• High-speed data bus architectures requiring bidirectional transfer
• Memory mapping and address decoding circuits
• General-purpose I/O expansion in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the suffix, noting that specific environmental declarations may vary by production batch. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-current drive capabilities alongside low power consumption. The FCT series offers compatibility with LVTTL logic levels, making it suitable for interfacing with modern digital controllers. Consider the 48-pin SSOP footprint for PCB layout constraints and verify thermal management requirements for the specified operating temperature range.

Part Context

This device is part of the broader 74FCT family of high-speed CMOS logic products manufactured by Texas Instruments. The family emphasizes performance improvements over standard TTL while maintaining pin compatibility. The 162245 variant specifically addresses applications needing dual-channel isolation and controlled data flow directionality in complex digital environments.

Replacement Considerations

Cross-reference with equivalent parts such as PI74FCT162245T from Diodes Incorporated or IDT74FCT162245ETE from Integrated Device Technology. Verify electrical characteristics, package dimensions, and pinout configurations to ensure functional compatibility during replacement scenarios.
