74LVC244ABX,115

Overview

The Nexperia 74LVC244ABX,115 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V. The device provides balanced propagation delays and includes overvoltage tolerant inputs capable of withstanding up to 5.5 V. It supports mixed voltage environments and offers high noise immunity with low CMOS power dissipation. The component is specified for operation across temperatures from -40 °C to +125 °C.

Feature Summary

• Octal buffering with two independent four-bit sections
• Three-state output control via dedicated enable pins
• Overvoltage tolerant inputs for mixed-voltage translation

Applications

• Mixed voltage bus driving applications
• Memory address and data bus drivers
• Clock distribution buffers

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure compatibility with target operating temperature ranges and input voltage levels before integration. Cross-reference ordering codes with current distributor catalogs to confirm availability status.

Selection Notes

Select this component when eight buffered outputs are required in a compact form factor. The wide supply voltage range allows flexibility in system design. Overvoltage tolerance simplifies interfacing between different logic families without additional level shifting components.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It serves as a standard solution for signal buffering in portable and battery-powered electronics. The series is designed to meet JEDEC standards for various supply voltage nodes.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74LVC244AD or 74LVC244PW from the same manufacturer. Verify that substitute parts maintain identical electrical characteristics and package dimensions.
