74LVT2244PW,118

Overview

The Nexperia 74LVT2244PW,118 is a BiCMOS octal buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and includes integrated 30 Ω series termination resistors in both HIGH and LOW output states to reduce line noise. The device provides overvoltage tolerant inputs up to 5.5 V and supports direct interface with TTL levels. It utilizes bus hold data inputs to eliminate external pull-up requirements for unused pins.

Feature Summary

• Integrated 30 Ω series termination resistors in output stages to minimize signal reflections and line noise
• Bus hold functionality on data inputs prevents floating states without requiring external pull-up resistors
• IOFF circuitry enables partial power-down mode operation to limit leakage current during system standby

Applications

• Memory address drivers
• Clock drivers
• Bus receivers and transmitters

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the application environment remains within the specified operating temperature range of -40 °C to +85 °C. Ensure input signals do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage to the device.

Selection Notes

Select this component when designing systems requiring an octal buffer with built-in termination resistance. It is suitable for applications needing direct interfacing between 3.3 V logic and 5 V tolerant buses. Consider the TSSOP-20 package constraints regarding thermal dissipation and board space availability during layout planning.

Part Context

This part belongs to the 74LVT logic family, designed specifically for low-voltage 3.3 V applications. It serves as a high-speed buffer solution compatible with standard TTL logic levels while maintaining low power consumption characteristics typical of BiCMOS technology used in modern digital interfaces.

Replacement Considerations

The 74LVT2244MTC from onsemi is a documented alternative. Verify pin compatibility and electrical specifications before substitution.
