54FCT244TLB

Overview

The 54FCT244TLB is an octal buffer and line driver manufactured by Renesas Electronics Corporation. It belongs to the FCT logic series and features eight input lines and eight output lines with non-inverting polarity. The device is housed in a 20-pin SOIC package. It operates within a power supply voltage range of 4.75 V to 5.25 V. The component supports a low-level output current of 64 mA and a high-level output current of 15 mA. Static current consumption is specified at 10 µA, while operating supply current is 5 mA. The functional temperature range extends from -40 °C to +85 °C.

Feature Summary

• Provides buffering and line driving capabilities for digital signals
• Features three-state outputs for bus isolation
• Supports standard CMOS logic levels

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering applications

Procurement Notes

Verify the specific manufacturer designation as IDT or Renesas, noting that IDT was acquired by Renesas. Confirm the RoHS compliance status and lead finish details against the latest datasheet revision. Ensure the package type matches the required PCB footprint and verify the operating temperature grade for the intended environment.

Selection Notes

Select this component when an octal buffer with high drive capability is required for system buses. The 64 mA low-level sink current makes it suitable for driving multiple loads or capacitive traces. Verify compatibility with the system's 5V logic family and ensure the 20-pin SOIC package fits the design constraints.

Part Context

This part is part of the FCT (Fast CMOS) logic family, designed for high-speed operation with CMOS compatibility. It serves as a critical interface component in digital systems requiring signal integrity and bus management. The octal configuration allows for efficient handling of wide data paths in parallel architectures.

Replacement Considerations

Check for direct equivalents such as the 74FCT244 variants from other manufacturers. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may have different packaging or temperature ratings.
