74LVCH244ABX,115

Overview

The Nexperia 74LVCH244ABX,115 is a non-inverting buffer and line driver belonging to the LVCH logic family. It features two independent elements, each handling four bits with three-state outputs. The device operates within a supply voltage range of 1.2 V to 3.6 V and utilizes a 20-DHXQFN package measuring 4.5x2.5 mm. It supports operation temperatures from -40 °C to +85 °C or +125 °C.

Feature Summary

• Provides bidirectional data transmission capabilities through dual four-bit buffers
• Features three-state outputs to facilitate bus-oriented connections
• Designed for low voltage applications with CMOS low power dissipation characteristics

Applications

• Bus-oriented systems requiring level translation
• Memory and microcontroller interfacing
• High-speed data transmission lines

Procurement Notes

Verify the specific suffix and package variant against official Nexperia documentation to ensure compatibility. Confirm availability status as some listings indicate obsolete status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production lifecycle stage before procurement.

Selection Notes

Select this component when designing circuits requiring non-inverting buffering with three-state control in low voltage environments. Ensure the system supply voltage remains within the specified 1.2 V to 3.6 V range. Consider the thermal performance and package size constraints associated with the DHXQFN form factor during PCB layout planning.

Part Context

This component is part of the broader 74LVCH series of logic ICs manufactured by Nexperia. It shares functional similarities with other octal buffers like the 74LV244 but differs in bit configuration and packaging. The LVCH family is optimized for low voltage operation while maintaining high speed performance suitable for modern digital interfaces.

Replacement Considerations

Direct substitutes may include other 74LVCH244 variants with compatible pinouts. Verify electrical specifications and package dimensions carefully. Some sources list related parts like 74LVCH244ABX as obsolete; check current Nexperia recommendations for active replacements.
