3 Description

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 currentdrive

capability of 8 mA to reduce line reflections,

overshoot, and undershoot caused by high-drive

outputs.
