74LCX07SJX

Overview

The Fairchild Semiconductor 74LCX07SJX is a hex buffer and line driver featuring low-voltage CMOS technology. It operates within a supply voltage range of 2V to 5.5V and utilizes a 14-pin Small Outline Package (SOP). The device contains six non-inverting buffer elements, each configured with one bit per element. It provides open-drain outputs capable of sourcing up to 24mA. The component supports a load capacitance of 50 pF and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Hex buffer configuration with six independent non-inverting channels
• Open-drain output architecture for flexible interfacing
• Low-voltage operation compatible with 2V to 5.5V power supplies
• High drive capability supporting 24mA output current

Applications

• General-purpose buffering in digital logic circuits
• Line driving applications requiring open-drain termination
• Interface circuits between different voltage domains
• Bus driver implementations in embedded systems

Procurement Notes

Verify the specific package variant against the datasheet, as the SJX suffix denotes a 14-pin SOP form factor distinct from TSSOP options. Confirm RoHS compliance status and lead-free certification requirements prior to integration. Ensure the open-drain output characteristics align with the target circuit design, particularly regarding pull-up resistor selection and voltage level compatibility.

Selection Notes

Select this component when a hex buffer with open-drain outputs is required for low-voltage applications. The 74LCX series offers superior speed and lower power consumption compared to standard HC or HCT logic families. Consider the 14-pin SOP package constraints for PCB layout and thermal management. Verify that the 24mA drive current meets the load requirements without exceeding absolute maximum ratings.

Part Context

The 74LCX07 belongs to the LCX family of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. This series is designed for high-speed operations with reduced power dissipation. The 74LCX07 specifically provides non-inverting buffering functionality. The SJX designation indicates the specific surface-mount packaging style used for this particular part number within the broader product line.

Replacement Considerations

Cross-reference with MC74LCX07DT from onsemi for equivalent functionality in a TSSOP package. Verify pinout compatibility and electrical specifications before substitution. Note that package dimensions differ between SOP and TSSOP variants, requiring mechanical review during replacement.
