74LVTH16501MEA

Universal Bus Functions Overview

The 74LVTH16501MEA is an 18-bit universal bus transceiver manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 2.7V to 3.6V and supports LVTTL/CMOS input levels with GTL/LVCMOS output levels. The device provides high drive capability with output currents of 32mA for low states and 64mA for high states. It is housed in a 56-SSOP package (0.295 inch width) and functions across an industrial temperature range of -40°C to 85°C. This component is classified as obsolete.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional data transmission capability for universal bus applications.
• Features high-drive push-pull outputs suitable for driving heavy capacitive loads.
• Supports mixed-voltage operation between 3.3V systems and other logic families.

Universal Bus Functions Applications

• High-density data buses in embedded systems
• Memory interface connections
• General-purpose 18-bit bus transceivers

Universal Bus Functions Procurement Notes

This part number is officially marked as obsolete and no longer manufactured by onsemi. Procurement must rely on secondary market distributors or verified surplus stock. Verify the authenticity of the source due to the discontinued status. Ensure that any available units are genuine components from authorized channels to avoid counterfeit risks associated with end-of-life parts.

Universal Bus Functions Selection Notes

Designers requiring this specific 18-bit LVTH transceiver should consider pin-compatible alternatives from other manufacturers. Evaluate current availability and lead times carefully since the primary manufacturer has ceased production. Review electrical specifications of potential substitutes to ensure compatibility with existing system voltage levels and drive requirements.

Universal Bus Functions Part Context

The 74LVTH16501 belongs to the 74LVTH series of low-voltage CMOS logic devices. It is designed for high-speed applications requiring robust signal integrity. The MEA suffix indicates a specific tape-and-reel packaging configuration offered by the original manufacturer before discontinuation.

Universal Bus Functions Replacement Considerations

Texas Instruments offers the SN74LVTH16501DGGR and SN74LVTH16501DLR as similar functional replacements. These parts share the same logical function but may differ in packaging or manufacturing origin. Verify pinout compatibility before integration.
