Overview
The 74AVCH1T45GM,115 is a dual-supply voltage level translator/transceiver produced by NXP Semiconductors, now part of Nexperia. This single-bit transceiver is designed to enable bidirectional level translation between two different voltage domains. It features active bus hold circuitry, which holds unused or floating data inputs at a valid logic level, eliminating the need for external pull-up or pull-down resistors. The device is fully specified for partial power-down applications using IOFF circuitry, preventing backflow current when powered down.
