74LVTH16501MEAX

Universal Bus Functions Overview

The Fairchild Semiconductor 74LVTH16501MEAX is a 3.3V ABT (Advanced BiCMOS Technology) 18-bit universal bus transceiver. It features three-state outputs and supports mixed-voltage operation, allowing interface between 3.3V systems and 5V environments. The device utilizes advanced BiCMOS technology to achieve high-speed performance comparable to 5V ABT devices while maintaining low power dissipation characteristics suitable for modern low-voltage applications.

Universal Bus Functions Feature Summary

• Supports mixed-voltage operation for interfacing 3.3V systems with 5V environments
• Utilizes Advanced BiCMOS technology for high-speed operation similar to 5V ABT
• Features three-state outputs to prevent bus contention during live insertion or extraction

Universal Bus Functions Applications

• Mixed-voltage bus architectures requiring level translation between 3.3V and 5V domains
• High-speed data transmission in portable and battery-powered equipment
• General-purpose 18-bit bus transceivers in computing and industrial control systems

Universal Bus Functions Procurement Notes

Verify the specific suffix MEAX against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and lead-free status requirements for your assembly process. Cross-reference the ordering information with official Fairchild or ON Semiconductor documentation to avoid discrepancies in pinout or electrical ratings.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface is required between voltage domains of 3.3V and 5V. The Advanced BiCMOS technology offers a balance of speed and power consumption superior to standard CMOS alternatives. Consider the three-state output capability if the design involves shared bus lines where multiple drivers must be isolated during non-active periods.

Universal Bus Functions Part Context

This part belongs to the LVTH series of logic ICs from Fairchild Semiconductor, designed for low-voltage applications. The LVTH series leverages BiCMOS technology to provide performance levels approaching traditional 5V ABT logic while operating at lower supply voltages. This places it within the broader category of universal bus transceivers used for system interconnects.

Universal Bus Functions Replacement Considerations

Check for equivalents such as the SN74LVTH16501 from Texas Instruments, which shares similar functional specifications and voltage compatibility. Verify pin-to-pin compatibility and electrical parameters before substitution.
