74VCXH245MTC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74VCXH245MTC is an octal bidirectional transceiver featuring non-inverting logic and three-state outputs. Designed for low-voltage applications, it operates within a supply voltage range of 1.2V to 3.6V. The device incorporates patented Quiet Series technology to reduce noise and electromagnetic interference (EMI). It utilizes advanced CMOS fabrication to ensure high-speed operation while maintaining low power dissipation. The component includes active bus-hold circuitry on data inputs, which eliminates the need for external pull-up or pull-down resistors to maintain valid logic levels on unused or floating inputs.
