74FCT245ATQG8

Buffers, Drivers, Receivers, Transceivers Overview

The Renesas Electronics Corporation 74FCT245ATQG8 is an octal bus transceiver belonging to the FCT logic series. It features a single functional unit with eight bidirectional channels and non-inverting polarity. The device utilizes a 20-pin QSOP surface-mount package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input and output levels. Key electrical characteristics include a maximum propagation delay of 4.6 ns at 5 V with a 50 pF load, a high-level output current of -32 mA, and a low-level output current of 64 mA. The component functions reliably across an industrial temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission through eight independent channels controlled by a direction signal.

• I/O expansion modules requiring isolated data transfer

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'QG8' against official Renesas documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance certificates matching the current manufacturing standards. Cross-reference the manufacturer part number with authorized distributor databases to confirm active status and avoid obsolete inventory substitutions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring robust octal data transfer between different logic domains. The FCT series offers faster switching speeds compared to standard LS logic while maintaining CMOS power efficiency. Consider the 20-QSOP package dimensions for PCB layout constraints and verify thermal dissipation requirements for high-density assemblies operating near the upper temperature limit.
