74LVCH322244AEC:55

Overview

The 74LVCH322244AEC:55 is a 32-bit non-inverting buffer and line driver manufactured by NXP USA Inc. It features 3-state outputs controlled by active LOW enable inputs (nOE). The device incorporates integrated 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise. It supports a wide supply voltage range from 1.2 V to 3.6 V and provides 5 V tolerant inputs and outputs for interfacing with 5 V logic systems. Inputs can be driven from either 3.3 V or 5 V devices, allowing operation in mixed voltage environments.

Feature Summary

• Integrated 30 Ω series termination resistors in output stages to minimize line noise
• Bus hold functionality on all data inputs to maintain valid logic levels without external pull-up resistors
• 5 V tolerant inputs and outputs enabling direct interface with 5 V logic in mixed voltage systems
• Low inductance multiple power and ground pins designed to reduce noise and ground bounce

Applications

• Mixed 3.3 V and 5 V system interfacing
• High-speed bus buffering applications
• Line driving in digital communication circuits
