74LVT2244D,118

Overview

The Nexperia 74LVT2244D,118 is an octal buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device incorporates 30 Ω series termination resistors in both HIGH and LOW output states to reduce line noise. It provides two output enables (1OE and 2OE), each controlling four outputs. Inputs include bus hold functionality to eliminate external pull-up requirements for unused pins. The component supports live insertion and extraction via IOFF circuitry.

Feature Summary

• Integrated 30 Ω series termination resistors in output stages to minimize signal reflections and line noise
• Bus hold data inputs that maintain logic state without requiring external pull-up resistors
• IOFF circuitry enabling partial power-down mode and supporting live insertion operations

Applications

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

Procurement Notes

Verify the package type matches the design requirement, as the D suffix indicates SO20. Confirm the ordering code includes the correct trailing digits for tape and reel quantities if applicable. Ensure the operating environment stays within the specified -40 °C to +85 °C temperature range. Check for RoHS compliance status on the specific batch documentation before integration.

Selection Notes

Select this component when 3.3 V logic buffering requires integrated termination to improve signal integrity. The bus hold feature simplifies board layout by removing passive components for floating inputs. Verify input voltage tolerance allows interfacing with 5 V systems despite the lower supply voltage operation.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage applications. It functions as an octal buffer or line driver with high-speed BiCMOS technology. The device is suitable for mixed-voltage environments due to overvoltage tolerant inputs. It serves as a standard interface solution for digital bus architectures.

Replacement Considerations

The 74LVT2244PW,118 is a pin-compatible alternative using the TSSOP20 package instead of SO20.
