IDT74LVC244APGG8

Overview

The IDT74LVC244APGG8 is a 3.3V CMOS octal buffer and line driver featuring 3-state outputs with ±24mA drive capability. It operates within an extended voltage range of 2.7V to 3.6V and supports industrial temperatures from -40°C to +85°C. The device utilizes 0.5-micron CMOS technology for low power consumption, offering rail-to-rail output swing and 5V tolerant I/O. Packaged in a 20-pin Thin Shrink Small Outline Package (TSSOP), it provides high-impedance states during power-up or power-down when OE is tied to VCC.

Feature Summary

• Provides 3-state outputs with ±24mA drive strength for moderate to heavy loads
• Features 5V tolerant inputs and outputs suitable for mixed voltage systems
• Supports hot insertion and ensures high-impedance state during power transitions

Applications

• 5V and 3.3V mixed voltage systems
• Data communication systems
• Telecommunication systems

Procurement Notes

Verify the package code PGG corresponds to the TSSOP-20 configuration and confirm the suffix indicates lead-free compliance. Ensure the ordering code matches the specific temperature grade and bus-hold requirements. Cross-reference the manufacturer's latest documentation to validate current production status and any potential design changes.

Selection Notes

Select this component for applications requiring robust signal buffering in mixed-voltage environments. The ±24mA drive capability allows direct interfacing with moderate loads without additional amplification. The 5V tolerance simplifies integration between 3.3V logic and legacy 5V peripherals, reducing system complexity.

Part Context

This part belongs to the LVC244A series of octal buffers/drivers manufactured by Renesas Electronics (formerly IDT). The series is designed for high-speed data transmission with low power dissipation. The specific model integrates standard 3-state control logic optimized for industrial temperature ranges and reliable operation in demanding electronic environments.

Replacement Considerations

Compatible substitutes include the 74FCT244ATSOG8 and QS3244, which offer similar octal buffer functionality. Verify pinout compatibility and electrical characteristics such as drive strength and voltage tolerance before implementation.
