74LCX760SJ

Overview

The Fairchild Semiconductor 74LCX760SJ is a low-voltage buffer and line driver featuring open-drain outputs. It contains eight non-inverting buffers with three-state capabilities, serving as the open-drain variant of the LCX244. The device operates within a supply voltage range of 2V to 3.6V and supports 5V tolerant inputs, facilitating interface between 5V systems and 3V systems. Packaged in a 14-pin SOP format, it utilizes advanced CMOS technology for high-speed operation while maintaining low power dissipation.

Feature Summary

• Features open-drain outputs suitable for bus-oriented applications
• Provides five-volt tolerant input levels for mixed-voltage system interfacing
• Includes three-state output control for efficient bus management

Applications

• Bus-oriented memory and signal driving
• Interfacing 5V systems with 3V logic circuits
• High-speed data transmission lines

Procurement Notes

Verify the specific suffix SJ against datasheet documentation to confirm package type and pinout compatibility. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer part number with current availability lists, as legacy components may have limited stock or require alternative sourcing strategies from authorized distributors.

Selection Notes

Select this component when open-drain functionality is required for wired-OR configurations or level shifting between different voltage domains. It is appropriate for designs needing high-speed buffering with low power consumption. Compare specifications against the standard LCX244 if push-pull outputs are sufficient, as the LCX760 offers specific open-drain advantages for bus sharing.

Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. It is functionally related to the LCX244 but differs by providing open-drain outputs instead of push-pull. The series is designed for high-speed operations with reduced power dissipation, making it suitable for portable and battery-operated applications requiring reliable signal integrity.

Replacement Considerations

The 74LCX760WMX is a documented equivalent part number offering similar low-voltage buffer characteristics. Verify pin compatibility and electrical parameters before substitution. Other variants within the 74LCX family may share logical functions but differ in package styles or output types.
