74VHC244M – FSC

Overview

The onsemi 74VHC244M is a high-performance, non-inverting buffer featuring 3-state outputs, designed to facilitate signal integrity in complex digital systems. Its key operational characteristic is its ability to drive significant capacitive loads while maintaining sharp signal transitions, crucial for high-speed data paths. A critical design consideration when implementing this device is managing the power-up sequencing to prevent output contention, as the 3-state capability, while advantageous for bus sharing, requires careful control to avoid unintended current paths. This buffer is integral for signal conditioning and distribution in applications demanding robust logic level translation and impedance matching.
