Overview
The 74AVCH1T45GW-Q100H, produced by Nexperia USA Inc., is a single-bit, dual-supply voltage level translator/transceiver. This device is designed to enable bidirectional level translation between two different voltage domains, making it highly versatile in various electronic systems. It features active bus hold circuitry to maintain valid logic levels on unused or floating data inputs, eliminating the need for external pull-up or pull-down resistors. The device is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
