Overview
The 74AVC1T45GM-Q100H, produced by Nexperia USA Inc., is a single-bit, dual-supply voltage level translator/transceiver with a 3-state output. This device is designed to enable bidirectional level translation between different voltage levels, making it highly versatile for various electronic systems. It features two 1-bit input-output ports (A and B), a direction control input (DIR), and dual supply pins (VCC(A) and VCC(B)), which can be supplied at any voltage between 0.8 V and 3.6 V. This flexibility allows the device to translate between multiple low voltage nodes such as 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
The device is fully specified for partial power-down applications using IOFF circuitry, which prevents damaging backflow current when the device is powered down. It is also qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications.
