74VCX16722MTD

Overview

The Fairchild Semiconductor 74VCX16722MTD is a 16-bit buffer and line driver featuring 3-state outputs, designed for high-speed data transmission. It operates within a supply voltage range of 1.2V to 3.6V and supports data rates up to 200 Mbps. The device utilizes an advanced CMOS process to achieve low power consumption while maintaining signal integrity over long traces. Packaged in a 48-pin TSSOP (0.49mm body width) surface-mount configuration, it includes independent output enable controls. Key electrical characteristics include a maximum propagation delay of 0.5ns at 3.3V and robust ESD protection exceeding 2kV per the Human Body Model specification.

Feature Summary

• Supports 1.2V to 3.6V operation for flexible system integration
• Provides 16-bit buffering with 3-state outputs for bus isolation
• Features low power consumption suitable for portable applications
• Includes independent output enable control for each direction

Applications

• High-speed data buses in embedded systems
• Memory interface buffering
• Portable electronic devices requiring low voltage operation
• Industrial communication interfaces

Procurement Notes

Verify the specific suffix 'MTD' corresponds to the 48-pin TSSOP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure that the operating temperature range meets your application requirements, as industrial grades may differ from commercial variants. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Selection Notes

Select this component for designs requiring 16-bit wide data paths with low voltage compatibility. Consider the 3-state output capability for shared bus architectures where multiple drivers must coexist. Evaluate the propagation delay specifications against your system timing constraints. Compare power dissipation requirements with other logic families to optimize thermal performance in compact enclosures.

Part Context

This part belongs to the VCX family of 1.2V to 3.6V logic devices, offering enhanced speed and lower power compared to standard VHC series components. It serves as a critical interface element in mixed-voltage systems, bridging low-power processors with higher-voltage peripherals. The 16-bit configuration reduces pin count and board space compared to using multiple 8-bit buffers, simplifying layout and assembly processes.

Replacement Considerations

Check for direct equivalents such as the 74VCX16722MTDX or similar variants from the same manufacturer family. Verify pinout compatibility and electrical parameters before substitution. Consult official replacement guides for any updated packaging options or lead-free specifications.
