74LVC241AD,118

Overview

The 74LVC241AD,118 is an octal non-inverting buffer and line driver manufactured by Nexperia (formerly NXP) in the SO20 plastic small outline package. It operates within a supply voltage range of 1.2 V to 3.6 V and features Schmitt trigger inputs for improved noise immunity. The device provides 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V logic systems while powered at lower voltages. It includes two independent output enable controls (1OE active LOW, 2OE active HIGH) managing high-impedance states.

Feature Summary

• Octal non-inverting buffer/line driver configuration with dual control enables
• 5 V tolerant inputs and outputs for mixed-voltage system compatibility
• Schmitt trigger action on all inputs to handle slow signal transitions
• High-impedance OFF-state when VCC is zero or outputs are disabled

Applications

• Translating signals between 3.3 V and 5.0 V logic domains
• Driving high-capacitance or long transmission lines
• Interface buffering in mixed-voltage embedded systems

Procurement Notes

Verify the manufacturer designation as Nexperia USA Inc., reflecting the corporate separation from NXP Semiconductors. Confirm the specific suffix 'AD' corresponds to the SO20 package variant with a -40 °C to +125 °C temperature range. Ensure compliance with RoHS standards and JEDEC specifications relevant to the target operating voltage.

Selection Notes

Select this component when an octal buffer with 5 V tolerance is required for low-voltage CMOS applications. The SO20 package offers a wider body width compared to SSOP or TSSOP variants. Consider the specific enable pin polarities (active LOW for channel 1, active HIGH for channel 2) during schematic design to match system control logic.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It serves as a buffer solution for systems requiring level shifting between 1.2 V and 3.6 V supplies and 5 V external interfaces. The 'AD' suffix specifically identifies the SO20 package option within the broader 74LVC241A product line.

Replacement Considerations

The datasheet lists 74LVC241ADB (SSOP20) and 74LVC241APW (TSSOP20) as alternative package options with identical electrical characteristics. No other functional substitutes are documented in the provided source material.
