74FCT16245LBETPA

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT16245LBETPA is a high-speed, low-power CMOS bus transceiver from the 74FCT logic family. It features dual independent 8-bit or single 16-bit bidirectional data paths with three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports TTL input and output levels. Key electrical parameters include a maximum propagation delay of 3.5ns at 50pF load, with output drive capabilities of -24mA (high) and 24mA (low). It functions reliably across an extended commercial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'LBETPA' against official manufacturer documentation to confirm package type, tape-and-reel specifications, and lead-free status. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm RoHS compliance requirements with the supplier prior to ordering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust 5V logic interfacing with high drive strength. The 74FCT series offers superior speed compared to standard FCT devices while maintaining CMOS power efficiency. Consider the 48-pin TSSOP package dimensions for space-constrained designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Integrated Device Technology (IDT) 74FCT logic portfolio, which provides fast CMOS performance as a replacement for older ABT functions. IDT, now part of Renesas Electronics, specializes in mixed-signal semiconductor solutions for computing and telecommunications markets.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include the PI74FCT16245ATV from Diodes Incorporated or the CD74FCT16245ATMT from Texas Instruments/Renesas. Verify pinout compatibility and electrical characteristics before substitution.
