74LVCH244AD,112

Overview

The 74LVCH244AD,112 is an octal buffer and line driver manufactured by Nexperia USA Inc. It operates within a supply voltage range of 1.65 V to 3.6 V. The device features two output enables (1OE and 2OE), each controlling four 3-state outputs. Inputs include Schmitt-trigger action for noise immunity. It is housed in a 20-SO package.

Feature Summary

• Octal buffer and line driver with 3-state outputs
• Wide supply voltage range from 1.65 V to 3.6 V
• Schmitt-trigger inputs for improved noise tolerance

Applications

• Memory mapping control
• Clock drivers
• Bus-oriented applications

Procurement Notes

Verify the specific suffix '112' against the official Nexperia datasheet to confirm the exact tape-and-reel packaging configuration. Ensure the operating temperature range matches the design requirements, as variations exist within the LVCH family. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when interfacing between 1.8 V or 3.3 V logic domains requiring high-speed buffering. The LVCH series offers lower power consumption compared to standard LVC devices. Verify that the input voltage levels are compatible with the driving source, considering the Schmitt-trigger characteristics.

Part Context

This part belongs to the Nexperia 74LVCH family of low-voltage CMOS logic. It is functionally similar to other octal buffers like the 74LVC244 but optimized for lower voltage operation. The 'AD' indicates a surface-mount SO package, while '112' specifies the packaging variant.

Replacement Considerations

Check for direct pin-compatible substitutes such as the 74LVC244AD if higher voltage tolerance is acceptable. Verify electrical specifications against alternatives like the 74AHC244 for speed differences.
