FCT162245TPV

Overview

The IDT FCT162245TPV is a dual bus transceiver from the 74FCT logic series, housed in a 48-pin SSOP package. It features two independent 8-bit bidirectional channels with true output polarity and TTL-compatible input/output levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 3.5 ns at a load capacitance of 50 pF. It provides high drive capability with output currents up to 24 mA and functions reliably across an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Dual-channel architecture providing two independent 8-bit bidirectional data paths for efficient system interconnects.
• True output polarity ensures non-inverted signal transmission between source and destination buses.
• TTL-compatible interface allows direct interfacing with standard digital logic families without level shifting.

Applications

• High-speed memory bus interfaces
• Microprocessor-to-peripheral communication links
• Bidirectional data buffering in embedded systems

Procurement Notes

Verify the specific suffix 'TPV' against official manufacturer documentation to confirm the exact package variant and material composition. Ensure compatibility with existing PCB footprints, as pin configurations may vary slightly between SSOP and TSSOP styles. Confirm RoHS compliance status through current datasheets, as manufacturing processes and environmental certifications can change over time.

Selection Notes

Select this component when a dual 8-bit bidirectional buffer is required with TTL compatibility and moderate speed requirements. The 74FCT series offers faster switching speeds than standard 74LS logic while maintaining similar power consumption profiles. Consider the 48-pin SSOP package constraints regarding board space and thermal dissipation capabilities during the design phase.

Part Context

This part belongs to the Integrated Device Technology (IDT) 74FCT family, which bridges the performance gap between CMOS and bipolar technologies. The FCT162245 specifically addresses applications requiring multiple bidirectional data transfers. IDT was acquired by Renesas Electronics, so current technical support and documentation are managed under the Renesas portfolio.
