74LCXH162244MTD

Overview

The onsemi 74LCXH162244MTD is a low voltage 16-bit buffer and line driver featuring active bushold inputs and integrated series output resistors. It operates within a supply voltage range of 2.0V to 3.6V, with outputs capable of interfacing with 5V signal environments. The device provides non-inverting buffering with 3-state outputs controlled by four independent nibble enable signals. It utilizes advanced CMOS technology for high-speed operation while maintaining low power dissipation.

Feature Summary

• Active bushold circuitry on data inputs eliminates the need for external pull-up or pull-down resistors to maintain valid logic levels.
• Integrated equivalent series resistance in outputs reduces overshoot and undershoot without requiring external termination components.
• Five-volt tolerant control inputs and outputs allow safe interfacing between low voltage logic and 5V signal environments.
• Nibble-controlled architecture enables independent management of four-bit groups or unified full 16-bit operation.

Applications

• Memory address drivers
• Clock drivers
• Bus oriented transmitter/receiver applications
