74FCT3244QG

Buffers, Drivers, Receivers, Transceivers Overview

The Renesas Electronics Corporation 74FCT3244QG is an octal buffer and line driver belonging to the FCT logic series. It features eight non-inverting inputs and outputs housed in a 20-pin QSOP package. The device operates on a single power supply ranging from 4.75 V to 5.25 V, with a typical operating temperature range of -40°C to +85°C. Key electrical characteristics include a propagation delay of 4.8 ns, high-level output current of -15 mA, and low-level output current of 64 mA. Static current is specified at 10 uA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer capabilities between buses using standard 244 pinouts for compatibility.
• Offers isolation under power-off conditions to prevent interference during system standby or shutdown states.
• Supports voltage translation functions between different logic levels within mixed-voltage systems.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces requiring bus switching and signal buffering.
• Hot-swapping and hot-docking scenarios where circuit isolation is critical.
• Voltage translation applications between 5V and 3.3V domains.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors due to potential availability of obsolete or refurbished units. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for specific suffix variations that may indicate package or temperature grade differences. Ensure supply chain stability as end-of-life notifications may affect long-term production viability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with low propagation delay and high drive capability. Consider the 20-pin QSOP package constraints for PCB layout and thermal management. Evaluate power consumption requirements against the specified static and operating currents. Ensure input signals are compatible with the CMOS logic family voltage thresholds.
