74LCXH16244MTD

Overview

The Fairchild Semiconductor 74LCXH16244MTD is a 16-bit buffer and line driver featuring 3-state outputs, belonging to the LCX family. It operates within a supply voltage range of 2.0V to 3.6V and utilizes a 54-pin TSSOP package. The device provides non-inverting buffering for high-density digital systems.

Feature Summary

• Provides sixteen non-inverting buffers with 3-state output capability
• Designed for low-voltage applications with operation down to 2.0V
• Features nibble-controlled 3-state control inputs for flexible data routing

Applications

• Memory address drivers in computer systems
• Clock signal distribution networks
• Bus-oriented transmitter and receiver circuits

Procurement Notes

Verify the specific suffix 'MTD' against official Fairchild documentation to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the component matches the 54-lead TSSOP physical dimensions and pinout configuration required by the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when interfacing between 2.0V to 3.6V logic domains requiring sixteen buffered channels. It serves as a direct replacement for standard 74AC/ACT16244 devices where lower power consumption and reduced supply voltage are prioritized over higher drive current capabilities.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It shares functional similarities with the 74AC16244 but is optimized for lower voltage operation. The device integrates advanced CMOS technology to achieve high speed while maintaining low static power dissipation suitable for portable electronics.

Replacement Considerations

The 74AC16244 and 74ACT16244 are functionally similar 16-bit buffers. However, they typically require a 5V supply. Verify that the system voltage supports the 2.0V to 3.6V operating range of the LCXH variant before substituting.
