SN74LV1T126QDCKRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV1T126QDCKRQ1 is an automotive-grade single buffer gate with 3-state outputs and integrated voltage translation. It operates within a supply voltage range of 1.6 V to 5.5 V and supports data rates up to 150 Mbps at 5-V or 3.3-V VCC. The device features 5.5-V tolerant input pins, enabling both up-translation from lower voltages (e.g., 1.2 V) and down-translation from higher levels (e.g., 5.0 V). It is qualified under AEC-Q100 Grade 1 for operation between -40°C and +125°C.
