IDT74LVC244AQG

Overview

The IDT74LVC244AQG is a 3.3V CMOS octal buffer and driver featuring 3-state outputs, manufactured by Renesas Electronics under the IDT brand. It utilizes 0.5 micron CMOS technology and supports an extended voltage range of 2.7V to 3.6V. The device provides high output drive capability with ±24mA current ratings and includes 5V tolerant I/Os for mixed-voltage systems. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features 5V tolerant inputs and outputs suitable for mixed voltage environments
• Provides high output drive strength of ±24mA per line
• Supports hot insertion applications

Applications

• Mixed voltage systems combining 5V and 3.3V logic levels
• Data communication systems
• Telecommunication systems

Procurement Notes

Verify the manufacturer designation as Renesas Electronics or IDT on the component marking. Confirm the package type matches the specific suffix requirements. Ensure the operating temperature range aligns with industrial specifications. Check datasheet revisions for any updates to electrical characteristics or pin configurations before final integration.

Selection Notes

Select this component when driving moderate to heavy loads requiring ±24mA output current. It is appropriate for translating signals between 3.3V and 5V domains due to its input/output tolerance. Consider the 3-state functionality for bus isolation needs in data communication architectures.

Part Context

This part belongs to the LVC244A series of octal buffers and drivers. It is designed for asynchronous communication between data buses. The device organization consists of two 4-bit line drivers with separate output-enable inputs, allowing flexible control over data flow direction and state.

Replacement Considerations

Compatible replacements include standard 74LVC244 variants from other manufacturers that maintain the same pinout and electrical characteristics. Verify that substitute parts support the required 5V tolerance and ±24mA drive current.
