Single Power Supply Single Buffer GATE CMOS Logic Level Shifter, 1.6V to 5.5V,

The SN74LV1T34DBVR is a single power supply, low voltage CMOS Gate Buffer Logic Level Shifter, designed to operate across a wide voltage range for a variety of applications. The output level is referenced to the supply voltage and is able to support 1.8/2.5/3.3/5V CMOS levels, making it a versatile solution for interfacing between different logic families.

The input is designed with a lower threshold circuit to match 1.8V input logic at VCC = 3.3V, enabling 1.8V to 3.3V level up translation. Additionally, the 5V tolerant input pins allow for down translation, providing flexibility in mixed-voltage environments. The wide VCC range of 1.8V to 5.5V allows the generation of desired output levels to connect to controllers or processors.

The device is designed with a current-drive capability of 8mA to reduce line reflections, overshoot, and undershoot caused by high-drive outputs. It supports standard logic pinouts and is characterized up to 50MHz at 3.3V VCC. The input pins are 5V tolerant, and the device features latch-up performance exceeding 100mA per JESD 78, class II. The product is a green product with no Sb/Br, suitable for a wide range of industrial and consumer applications.
