Texas Instruments SN74LV4T125/SN74LV4T125-Q1 Buffer Translator Gates

Texas Instruments SN74LV4T125/SN74LV4T125-Q1 Quad Buffer Translator Gates are low-voltage CMOS buffer gates that operate at a wider voltage range for industrial, automotive, portable, and telecom applications. The output level can support 1.8V, 2.5V, 3.3V, and 5V CMOS levels and is referenced to the supply voltage.

The input is designed with a lower threshold circuit to match 1.8V input logic at VCC = 3.3V and can be used in 1.8V to 3.3V level-up translation. The 5V tolerant input pins also enable down translation (for example, 3.3V to 2.5V output at VCC = 2.5V). A wide VCC range of 1.8V to 5.5V allows the generation of desired output levels to connect to controllers or processors.

The Texas Instruments SN74LV4T125/SN74LV4T125-Q1 devices are designed with a current-drive capability of 8mA to reduce overshoot, undershoot, and line reflections caused by high-drive outputs. The SN74LV4T125-Q1 devices are AEC-Q100 qualified for automotive applications. The SN74LV4T125-EP devices have gold bond wires, a temperature range of –55 to +105°C, and an SnPb lead finish.
