74FCT3244SOG8

Buffers, Drivers, Receivers, Transceivers Overview

The Renesas Electronics 74FCT3244SOG8 is a 3.3V CMOS octal buffer and line driver housed in a QSOP-20 package. It features eight non-inverting input lines driving eight output lines. The device operates within a supply voltage range of 2.7V to 3.6V, with a maximum operating temperature of +85°C and a minimum of -40°C. Electrical characteristics include a high-level output current of -8 mA and a low-level output current of 24 mA. Static current is specified at 100 nA, while the operating supply current reaches 1.2 mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'QG8' against official Renesas documentation to confirm package type and material compliance. Ensure the operating environment stays within the 2.7V to 3.6V supply range. Confirm thermal limits align with the -40°C to +85°C specification. Cross-reference datasheet revisions to ensure compatibility with existing system designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer is required for 3.3V logic systems. The FCT series offers faster switching speeds compared to standard LS logic. Verify that the QSOP-20 package fits the PCB layout constraints. Ensure the load requirements do not exceed the specified 8 mA source and 24 mA sink currents.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FCT logic family, which bridges the speed of TTL with the power efficiency of CMOS. The 3244 designation specifically indicates an octal buffer configuration. Renesas continues the legacy of IDT FCT products, maintaining pinout compatibility while offering improved electrical characteristics for modern 3.3V applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the 74FCT3244ASOG8. Verify that any substitute maintains the same QSOP-20 footprint and 3.3V operation. Ensure the replacement supports the required 8-input/8-output configuration without changes to control logic.
