Single Power Supply Quadruple Buffer GATE w/ 3-State Output CMOS Logic Level Shifter

SN74LV4T125 is a low-voltage CMOS

buffer gate that operates at a wider voltage range for portable, telecom,

industrial, and automotive applications. The output level is referenced to the

supply voltage and is able to support 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels.

The input is designed with a lower

threshold circuit to match 1.8-V input logic at VCC = 3.3 V and can be

used in 1.8 V to 3.3 V level-up translation. In addition, the 5-V tolerant input

pins enable down translation (for example, 3.3 V to 2.5 V output at VCC =

2.5 V). The wide VCC range of 1.8 V to 5.5 V allows the generation of

desired output levels to connect to controllers or processors.

The SN74LV4T125 device is designed

with current-drive capability of 8 mA to reduce line reflections, overshoot, and

undershoot caused by high-drive outputs.
