54FCT244ATDB

Overview

The 54FCT244ATDB is an octal buffer and line driver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40 °C to +85 °C. The device features eight non-inverting input lines and eight corresponding output lines, housed in a 20-pin SOIC package. Electrical characteristics include a high-level output current of -15 mA and a low-level output current of 64 mA. Static current consumption is specified at 10 µA, with a maximum operating supply current of 5 mA.

Feature Summary

• Provides buffering and signal driving capabilities for digital logic circuits
• Features three-state outputs for bus isolation and system flexibility
• Supports standard FCT logic family compatibility

Applications

• Bus driver applications requiring signal integrity maintenance
• Clock distribution networks for timing signals
• Memory address and data bus buffering in computing systems

Procurement Notes

Verify the specific suffix 'ATDB' against the manufacturer's official datasheet to confirm pinout, package dimensions, and electrical tolerances. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the Renesas part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when an octal buffer with high drive capability is required for 5V logic systems. The 64 mA low-level output current supports heavy capacitive loads. Verify that the 20-pin SOIC package fits the PCB layout constraints. Confirm that the -40 °C to +85 °C temperature range aligns with the environmental conditions of the target application.

Part Context

This component belongs to the 74FCT series of Fast CMOS logic devices produced by Renesas Electronics. The series is designed for high-speed digital applications, offering performance comparable to TTL but with CMOS power efficiency. The 54FCT variant typically denotes extended industrial temperature ranges compared to commercial grade parts.

Replacement Considerations

Check for direct equivalents such as the IDT 54FCT244ATDB or other 74FCT244 variants from different manufacturers. Ensure replacement parts match the 20-pin SOIC package and maintain identical electrical specifications for voltage and current drive.
